With an account on blackjackandhookers.net you'll be able to follow people on any Mastodon server and beyond.

In an effort to foster more intimate community (aaannd keep overhead costs as low as feasible), this is at present an invite-only server

If you know somebody who has an account, then they should send you an invite ;-) *hint hint*

Otherwise, you can find other Mastodon communities to join and then explore our User directory
