Boost died for me at 7PM EDT on 6/30, along with the rest of Reddit. Apparently, Reddit was incompetent with disabling everything, so it (along with other 3rd party app) still worked for some people if you were not logged in.
I miss the niche subs I was a part of, I recreated them on Lemmy and hopefully they can gain some traction, I loved the discussions on those subs and I hope I can have the same experience on Lemmy. If not, life goes on.
It's kind of inconsistent for me. My only theory, based on something I saw on r/BoostForReddit, is that I'm still marked as a mod for an inactive sub. My alt doesn't load anything.
