return2ozma was banned because he was posting a nonstop flood of articles, and admitted to the mods that he basically just searched out bad stories about Biden and posted them whatever they were (even some ones he didn't try to defend any kind of factual accuracy of), to bring "balance."
I actually don't agree with making that the criterion. I think it's of a piece with lots of types of lazy and unproductive moderation that happpens on lemmy.world. But, I definitely agreed with banning him, for the same reason that I would expect to be banned if I went to your favorite community and posted 15 stories a day about "Five things you won't believe about what Biden accomplished during his term in office!" It's not about the viewpoint being prohibited from anyone expressing it (and, of course, the fact that we're having this conversation and you haven't been banned for expressing criticism of the Democrats is an obvious counterexample to you trying to say that's banned on LW). It's about one person spamming to try to promote it.
But I'm not trying to do additional work on your behalf right now. I just had a long day and I'm done working for now.
You said anyone could do it, you said it was super easy, just from memory. We'd be having a different conversation if you'd said "Anyone who felt like taking a bunch of time away from their job could probably put together a script to comb through the whole database to find the single example you're looking for, because I'm sure at least one exists, although I can't do that whole endeavor right now I'm confident that it would work if someone did do it. I'm very tired and such a thing would be horrifying and unfair if someone asked me to do it. I just know some other person who had a lot of energy to spare could."
