The best way to provide ! links that work for the most people is just to type them out as plain text, not as a hyperlink to anything.

So, these communities can be found at:

!roughromanmemes@piefed.social

!politicalcompassmemes@piefed.social

!inhabitedbeauty@piefed.social

!tankiejerk@piefed.social

!historyphotos@piefed.social

!historyart@piefed.social

!historyartifacts@piefed.social

!historyruins@piefed.social

!shermanposting@piefed.social

!noncredibledefense@piefed.social

Also, from what I can tell, they haven't been moved using PieFed's community migration facility (which squishes the old remote community into a new local one and retains the history (e.g. like what happened with like !casualconversation@piefed.social ). These are just brand new communities, starting from scratch.
