You are not the asshole. The purpose of that community is to have communication with humans. When a bot posts a question there, there is no reason to respond. It's not a human asking, and the human that originally asked in another forum will never see the response. I blocked that spammy bot, and have enjoyed my feed way better since.

NTA, that shouldn't rob your sleep tho, it's something that will happen, and kind of inevitable once reaching critical mass.

Despite that, I think there is nothing wrong with wanting to migrate useful content from dedicated communities into a safer, better platform. If you think about it, that content was never Reddit's, It was from the community, for the community.

People reposting low effort content and memes for engagement kinda suck tho.

I hate that bot SO MUCH. It's the only account i have blocked on Lemmy.

No. I see a lot of reposts in here, even with meme templates 13 years old, and I’d rather not see them at all

NTA.

AITA is not about sharting funny content and then asking "am I an asshole or what", it's a way for the OP to invite (hopefully) honest and civilized discussion and criticism about their actions, without risking verbal abuse or being downvoted to hell. When a bot reposts an existing question without the OP's knowledge, it loses the line of communication between OP and the community and the entire point of an AITA post. Populating the fediverse with content is important, but compromising the entire reason that content exists is not the way to build a community.

edit: sharing, not sharting. I'm not changing it because funny.
