Definitely Facebook's policy of demanding real world names and crushing down on anonymity and pseudonyms, around 2014: https://www.protocol.com/policy/anonymity-real-names-jeff-kosseff#toggle-gdpr

Yes, started using it about a year ago and it's amazing how much easier it is.

I found some of them:

!atbge
!kidsarefuckingstupid
!cologne
!djs
!deephouse
!housemusic

I'm a sucker at using the kbin / Lemmy search. I am still looking for these communities:

/r/atbge
/r/justfuckmyshitup
/r/catsareassholes
/r/thecatdimension
/r/KidsAreFuckingStupid
/r/cologne or / r/koeln
/r/parents or /r/eltern
/r/djs or /r/beatmatch
/r/house or /r/deephouse

There are probably more... If noone knows where these communities exist on Lemmy or kbin, I will create them! Maybe you can help me deciding on which instance it would be best. I can do lemmy.ml, lemmy.world, feddit.de and kbin.

I am using Liftoff and Jerboa with lemmy.ml - I prefer Liftoff. Lemmy.ml is pretty slow recently.
I also have a kbin account with subscriptions to the same communities, and on mobile I am using the web app: Howto install a web app.

It says

User Count Bot for all known Mastodon instances

Is that not true? Does it count Lemmy and kbin users, too?
