"In the small town in Germany where the Nazi leader Rudolf Hess was born, every year right wing activist[s] have been showing up to commemorate his birthday. Counter marches didn't stop them. What really got to them was when people organized to sponsor donations on their behalf, treating their march like an AIDS walk. For every meter marched, there would be 10€ donated to anti-racist organizations. People then turned it into kind of a sports event as they showed up with banners and music cheering the fascists on like 'thank you for marching for racial justice' and updating with bullhorns how much money the fascists marching had already raised." – Yannik Thiem
Did fundraising for anti-nazi groups stop neo-nazis from marching in Hess's town?
A quick google search came up with news about the fundraising, but not about the annual marches stopping.
This question is probably about the successor marches to the infamous "Rudolf-Heß-Gedächtnismarsch" which had mainly been taking place in Wunsiedel, where Rudolf Heß had been buried until 2011, as well as about the internationally recognized, fundraising counter protest "Rechts gegen Rechts" which premiered in Wunsiedel in 2014.
I could find reports about Nazis marching in Wunsiedel for every year since the "Rechts gegen Rechts" campaign started in 2014:
(2017: Nazi rally planned in Berlin in November, 500 attendees expected. (Source as per Wikipedia))
The fundraising counter protest does not appear to have had an effect on the raw number of attendees, let alone did the marches stop. However, one source mentioned that the composition of the attendees had apparently changed from predominantly local Nazis to Nazis "imported" from other federal states.
