evacideOf all the communities I had on Twitter, Infosec Twitter is the group that moved to Mastodon and never looked back.

@evacide I think with so many communities focused on #infosec, it definitely helped draw infosec professionals over. Plus, a lot of these infosec focused instances have much larger character limits & moderation that imo is pretty friendly towards those in infosec.
We've got instances like infosec.exchange, infosec.town, cyberplace.social, noc.social, hachyderm.io, ioc.exchange, hackers.town and more to thank for hosting the infosec community on the #fediverse!
