PSA: there is a new fedi instance called mastodon[.]tech. Confusingly, it is running Pleroma. People behind it set up a @Tech account, and reached out to me (and I can only presume others).
I told them in private what I am telling everyone in public now: I find it very sketchy, based on the interaction with that account, and on mastodon.technology-lookalike domain.
I have on good authority they are in no way affiliated with or endorsed by mastodon.technology. I will stay away from them.
