If you're planning on continuing protesting there, then yes. Only dedicate any posts and comments to the protest and for protest purposes. Otherwise, the best thing to do is delete and move on. Like other comments said, it's all just traffic for them, however if you're going to be there anyway, you may as well be there for a cause.
PSA: anyone still looking to protest, promote fediverse, any form of rebellion ON REDDIT, the place to do it is r/pics. you can post anything with basically no censorship. as long as you mention John Oliver somehow, the mods aren't going to bother you! (kbin.social) en
r/pics is wide open to all kinds of anti reddit posts, calls for spez to resign, whatever you want with the current rules right now....
