If I can remember the order, it's
1) Poa.st, for like 3 months (account deleted)
2) Chudbuds (for 6 months until it got taken down)
3) Wideboys (for a day and never used because I just moved to Zztails instead, and now wideboys is gone so it's not like I can go back and delete the account)
4) Zztails (for 4/5 months until it got taken down, rip to one of the best instances there was)
5ish) Sneed.social (I made it as an alt in case zztails got taken down, which it did, but then so did sneed social because of the connection to Torswats and shit, so of all the instances I could've picked I chose the one that's shut down because of it's connection to swatters)
6) NCD for like a day before Fartkart (bless his heart) started shit with the wignats
7) Shitpost.cloud, my home for over a year now.
Lucky number 7 wins again.
