I see where this can be useful, but is this list categorized or at least indicate why a certain instance was added?
It's different blocking an instance for simply repeated toxic behavior vs political leanings. Sometimes an instance can have both.
Letting new admins know and select categories/tags to block or let through could be an improvement, if it isn't there already:
- NSFW (sometimes people want a SFW site, like browsing at work)
- NSFL (porn might be okay but not everyone have fond memories of ogrish.com and likes)
- Illegal in X jurisdiction (e.g. CSAM)
- Far right or far left
- Repeated instances of troll / spam bot accounts
- Abandoned by admin
