I hope you don't mind me asking, but I've seen the claim that lemmygrad.ml and lemmy.ml are run by the same person/team many times, and am wondering if you've found any sources on that? I'm not saying it's incorrect or the devs aren't problematic, I'm just trying trying to find a reputable source.
I've been trying to look myself, and so all I've found is that "someone" claims that lemmygrad.ml and lemmy.ml resolve to the same IP ( https://mstdn.social/@feditips/106839809077880828 ), which it doesn't as of June this year, and an uncited comment on whatever Prolewiki is.
