For WefWef users there isn’t a block button, however, switch to Memmy or Mlem and block them through that and it will also block in WefWef. Just wanted to throw that out there.

Glad I could help 🙂

I thought the same thing but the WefWef app lets me save my 3 Fediverse accounts and switch easily, idk if it would be same for any other apps though. This way if an instance decides to defederate I can still access their content separately.

!archive@lemmy.world is a community that reposts noteworthy Reddit posts onto the Fediverse so you presumably wouldn’t have any issues as long you’re giving credit to the OP.
