Yes, they do. They will also delete likes.
However, the comments quoted and the general complaints on that video about dislikes going away are based on the claim that Gillette is either paying YouTube to delete dislikes, or that Gillette is doing it, itself.
One reason why YouTube deletes some likes and dislikes is because people often use likes, dislikes, ...
YouTube itself says that it can remove dislikes. From Likes and Dislikes report:
You may see like/dislike counts change as some may be marked invalid and periodically removed from the counts. Learn more about our Likes Policy. [outdated link]
This number comes from W3Techs - World Wide Web Technology Surveys.
According to that survey, as of December 2016,

Below are points of evidence supporting the fact that sharks are a threat to undersea cables.
The first report of sharks attacking cables came from the Canary Islands in 1985, when sharks' teeth were found embedded in an experimental cable. I found the report in an old news paper.
According to a report by the United Nations Environment ...
That might be true in 2017, or at the beginning of the 2018 when UK analytics firm Cable published its speed table. Right now you can check the stats live.
And although Madagascar is still "faster" than UK only 7% of its population have access to the internet (compared to 94.6% in UK) according to this page.
According to a press briefing published on the official un.org, the website is not associated with the UN:
And just to note that over the weekend, I’ve been receiving a lot of questions from different journalists about a website for a something called the United Nations New World Order project. I just want to state and say this very ...
No, it's an Internet urban legend
"Marianas web" is an expression originating from an infographic first published on Imgur in 2011 that attempted to provide a classification of the deep web architecture.
According to this infographic, the web is divided in five layers, each more difficult to access, and the deepest is supposed to be "Marianas web".
(This answers addresses the original question, which was more focused on whether the site was legitimate or was just made to be fodder for conspiracy theories. The current version focuses on whether it is affiliated with the UN, and see tim's answer for a better answer to that using the official word from the UN)
It's a real website and appears to be owned ...
Sharks are an extremely small threat to undersea cable in regards to others causes as shown in the graphic below (from a report cited in @georgechalhoub's answer).
Proportion of cable faults by cause, from a database of 2,162 records spanning 1959–2006
Abrasion 3.7% ;
Geological 2.6% ;
As of July 2019 according to the Speedtest.net Global Index , Madagascar (unranked mobile, rank 68 fixed) ranks below all of the 3 listed countries: United Kingdom (rank 50 mobile, rank 41 fixed), France (rank 18 mobile, rank 15 fixed) and Canada (rank 6 mobile, rank 12 fixed).
Even in 2017 (August 2017 Wayback Machine data), it still ranks below all of ...
The facts of this situation are pretty well known. During his time in Congress, Gore played a vital role in the creation of the computer networking system that we know as 'the internet..

While there's no proof, this seems like an incorrect assertion.
Based on the wording, this most likely seems like either a typo (or simply a rather grammatically-challenged typist); or simply two independent targets to give certificate to (probably, the vendor and the asking unit).
The latter appears to have evidence backing it up by a series of similar ...
Yes, YouTube moderators can delete Likes and Dislikes.
Cinema of Change tracked the responses to the Gillette video over a short period.
With the help of YouTube’s API and Archive.fo’s screenshots of the video’s public numbers, we were able to test the claims of whether Gillette’s dislike and comment count were being subject to unusual moderator deletion.
I think it's a little ambiguous if this is on topic for Skeptics, since it relies on knowledge only Stack Overflow employees have.
So I posted a long answer on Meta Stack Overflow (we're only measuring on Stack Overflow) that goes into some detail about how we measure negative comments and the recent trends we have seen that lay behind Prashanth's comment ...
tl;dr- This appears to be based on a true story, however the overall narrative seems pretty misleading. In particular:
The farmer wasn't a one-man crusade.
The farmer didn't spend 16 years preparing to sue the chemical company.
The farmer didn't need to rely on his own legal expertise since he had a lawyer.
The factual background about a ...
It's been previously documented that "glitches" can also alter the like/dislike ratio on a large scale, for example, a Justin Bieber video (including, bizarrely, adding dislikes to likes), so it's entirely possible:
Given YouTube control the stats behind the scenes, they can ...
The claim is both misleading, and wrong from an objective point of view.
First, it is misleading because the numbers it refers to are the country's mean download speeds. In the objected countries, such as e.g. France (or even moreso Canada), a large number of people lives in rural, sometimes quite remote areas where, indeed, internet speeds are not always ...
The paper you link to is referring to 'Deep Web' meaning unindexed data, and it's claims may be roughly correct in this sense - at the time it was published. It's not referring to the Tor based network of hidden sites you also mention, however. The term DarkNet is often used for these sites, so for clarity, I will refer to 'Deep Web' when discussing normal ...
First let's answer this question.
What counts as a non-human "user" of the internet?
Any electronic device connected to the internet. There are numerous types of devices that can be connected to the internet. Be it a laptop, printer, iPod touch, server, cellphone, tablet, television, google glass, desktop computer, etc....

Yes, they do hire people to filter content.
I wasn't aware that this information could be considered controversial. It's not really a secret, it's called Commercial Content Moderation and most big companies who work with user content do it.

I selected Times New Roman as an example for this answer.
The Wikipedia page on Times New Roman does a better job than I could of explaining the history of the typeface, including that, yes, its owner, Monotype has a proprietary licence available for it.
Licenses can be purchased from Monotype. [I hope you will appreciate this is a reference to show that ...

The lifestyle website HelloGiggles describes how the hashtag started:
In 2010, Duval tweeted: “#itaintrape if u naked of Yo Twitter profile pic”, “#itaintrape if I’m paying child support”, “Lmao RT @MrCashFanatic: @lilduval #itaintrape if she doesn’t remember it.”
From there, his followers took the hashtag and ran with it.
With regards to this question,
How come arabs be so verbose in the field of chatting and be so unproductive in terms of internet content?
a possible answer comes from this sentence in the IWS site:

Most likely true
There is little doubt that first 3 languages are English, Chinese and Spanish.

The percent of (adult) men and women who use the internet is about the same in America.
According to data from the Pew Research Center, since the year 2000, the biggest gap was 66% men used the internet vs. 61% women in 2004. For several years the percents were equal (84%, 2013; 84%, 2014; 86%, 2015).
In 2018, 89% of men and 88% of women used the internet....
The original research that produced this was done in a collaboration between the University of Glasgow and the University of Oslo, and UoG details it here. While the Glasgow part is available here, the part we are interested in is available here, but is $30.
