A little peek into some very depressing happenings on 
See the first link at the bottom, for the main evidence dump and collation.
For a brief tldr, a convicted pedophile abuser, Brynn, got uncovered as a mod in a subreddit for trans women, /r/mtf. In leaked discord convos, the head mod, CedarWolf, was shown downplaying it, and suggesting they swap their account for a new, anonymous one. Cedarwolf is a mod on over 100 subreddits, most of them LGBT related.
With the news blown, instead of like dealing with it responsibly, they just locked down, deleted, and banned anyone who mentioned it on subreddits they controlled. They're going all in on damage control and pedo defense. They made a few posts trying to downplay the news as misleading or harassment, but the community was not accepting it. For a while, they locked the subreddit entirely, but apparently Cedarwolf stopped looking at it for a bit, as it's now entirely filled again with posts calling for them to resign.
The news stayed relatively quiet for a bit, but now it's to the point that Elon discovered it and is tweeting about it. Needless to say, this is fucked in so many ways. It's likely people were put at risk or harmed by the mod teams behaviors and actions, and it's also perfect propaganda bait for right wing shitheads as the news continues to slowly grow. Predictably, Reddit admins are choosing to stay uninvolved, given their "libertarian" lean.
(Also the pronoun use in regards to CedarWolf is deliberate. They aren't a trans woman, despite running a trans woman subreddit. They're he/they/she non-transitioning bigender).
I don't have the full list of all assorted evidence, as this is more just me being depressed and venting, but here's a few bits and pieces.
Main collection of evidence. User since deleted their account, so it's an archive link. Has pictures of discord screenshots, plus snips of the mod's sex offender registry. An ex, who's a reddit mod of /r/egg_irl, posted in the thread alleging that the modremovedd and abused her.
