Just a heads up, Lemmy is not immune to the same problem. If there are rogue moderators, just like Reddit the only option you have is to message the instance admin or other moderators. If theyre all on the same team and the instance admin doesnt respond or agrees with their behaviour, then you're in the same place you were with Reddit.
Also, Lemmy might have a chance at this being worse. AFAIK, on Reddit reports are anonymous. Moderators didnt know who reported what content. But on Lemmy, reports are NOT anonymous. While some argue this is helpful for identifying trolls/superfluous reporters, for the same reason it can also easily be weaponized by rogue moderators. The only thing Lemmy really has going for it is that its relatively small right now. But as its userbase grows, it will likely fall victim to the same user issues that Reddit has.
