I think defederation only really makes sense if there is a concern of botting. Individual bad actors should be banned on a case by case basis, blanket banning seems shortsighted. However, I do believe there are bots on some instances now, compared to say a year ago where I believe they were more far and few between.

Part of my issue is also with bad actors “flooding the zone”. If enough noise is getting pushed constantly by bad actors/bots, it can sway public opinion just by virtue of people seeing those opinions more often. This was one of the things that killed Reddit for me, personally. Well that and a slew of other issues.
