I had the same problem with lemmit.online, and with lemmit.online the owner said “yeah this is a bot, this whole instance is for reddit reposts, if you don’t like it defederate from me” - which .ca did.
I can’t stand bot instances or bots in general that are reposting from reddit, because it’s not valuable content for the fediverse - the OP doesn’t see what we’re saying and if we’re troubleshooting something that’s been crossposted it’s literally just on deaf ears.
The only bot I actually like is the ITNBot which is for ImproveTheNews - it posts neutral, pro-, and anti-stance information relevant to the article being posted, showing you all sides of the issue.
