Honestly I have a question I answered myself and was up for over 10 years with hundreds of views and votes only for the question to be marked as a duplicate for a question that verboten has nothing to do with the question I asked. Specifically I was working with canvas and svg and the question linked was neither thing. The other question is also 5 years newer so even if it were the same it would be a duplicate of mine, not the other way around.
Another one is a very high rated answer I gave was edited by a big contributor to add a participle several years after I wrote it and then marked as belonging to them now
Both times i issued a dispute only for it to be completely ignored. Eventually I used a scrubber bot to delete every contribution I ever made instead of letting random power mods just steal content on my high profile posts.
