Yeah, looks like the subreddit has been taken over completely. You can see that the original founder of the subreddit had resigned shortly before... and his farewell-post has been deleted by the new mods. The other mods all seem to be inactive, and going through one of their histories, I found them talking about being harassed and bullied a relatively few comments before ceasing /r/gifted comments
I brought this up in modmail with them, to see if any of the uncorrupted mods would respond, under their names. The responses denied my claims and mocked me, before banning me, but notably, all of the responses were under the group-mod username: so either none of the old mods were willing to respond under their usernames, or it wasn't the new mods responding. (Hint: it was almost certainly the latter.)
I reported it to the Reddit admins, but have heard nothing back. I don't expect too much because if the worst the new mods are doing is spamming affiliate links, that's relatively tame and far down the priority list.
