@anastas2002@dice.camp @CheekyKokako it is genuine, set up by a partner (not Pinnacle), because I had a few chats with their admin. They had originally copied an aggressive block list from elsewhere and Qoto (my instance) was on it.
They removed it, but I still can't follow, so not sure what the issue is (could be a version thing; Qoto is a bit behind/customised).
But worth checking why it is being flagged.. maybe the "@" in the URL ... or maybe it is a shared server used by bad actors?
Either way, I don't think following from the Fediverse would be affected. You can paste the URL into the search/follow box (not your browser), or try their account @peginc@savageworlds.social
@sgryphon @anastas2002 I was able to follow them just fine, so I'm not sure what the issue is.
