I would block gore communities on a personal level, but there's no need to do so on a server level unless they're doing something worth defederating for, like any of the following:

• posting cp
• using their server to DoS/DDoS others
• dox-ing people
• allowing their users to harass others AND refusing to punish such behavior
• same as above except for ban evasion

I'd like to have a force-nsfw option for communities that don't enforce proper usage of the NSFW tag, but for now I'd have to block them most likely.

Personally, I'm fine with a NSFW tag, and would hope that NSFW instances respect other instances enough to properly tag stuff.

Any instance with a gore community? Nah, screw that noise. Add it to the block list.
