I know probably not the perfect place to post this but want to get the discussion started and don’t know enough to be scared or not: because of the decentralization of Lemmy, is it extremely vulnerable to malicious/ad bots, astroturfing, spam and such?
My understanding is there isn’t one Lemmy. There are lots of instances, but they all talk to each other. I.e. they share the posts and comments their users make. If an instance becomes problematic then other instances will choose to stop receiving updates from them. So users of the bad instance can still see the content and comment on it, but other users won’t see the content from those users.
