Yeah, it took me a long time to realize because that user is extremely careful to always be superficially polite and always framing their actions as trying to help the fediverse, but I'm beginning to recognize that they're basically an energy vampire that just drags down the vibe of Lemmy with constant but what about or I don't fully agree replies.
They seem to make every discussion way more complicated and contentious than it needs to be. What is the point of constantly linking and posting about every single time that anybody has a disagreement on Lemmy? They would nominally say they do it to expose mod abuse or whatever, but it's typically fairly innocuous incidents that get blown way out of proportion. Mods aren't ever going to be perfect, and constantly putting them and also random users on blast is extremely unproductive, because you get a whole bunch of commenters who don't understand any of the nuance of the situation and inevitably get their pitchforks out, causing way more frustration and anger than the original situation would have caused otherwise.
They also never upvote anybody who replies to them, even when they occasionally claim to agree, which is extremely rare in itself. Who does that? Like how do you use Lemmy that much but consistently refuse to upvote the other users who are taking time out of their day to have a discussion with you? They make using Lemmy seem boring and tedious, which is really quite a remarkable accomplishment considering how many other interesting personalities we have on here. And they always sound extremely insincere when they performatively congratulate or thank others, often opting for a one word Nice! or Thanks. Like I said, energy vampire. I could go on, but you get the message. I do not like this user and I am suspicious of their intentions.
