It's important that reddit Admin/Legal know who Joe is and how he's threatened to dox and beat up redditors. I put together this list of Joe's doxxing and threatening redditors. Most of the links are to banned subs or Joe's deleted comments, but Reddit staff should be able to look them up.

He's appears to have DMCA'd many fair-use items and many things he has no copyright on including a still image from a television show (The People's Court) owned by Warner Bros. He has DMCA'd numerous re-postings and links to his own reddit comments which appears to violate Reddit's ToS which grants Reddit the rights to host that content on Reddit owned properties forever. His main goal in filing DMCAs is likely to dox reddit users he does not like and harass them, which he's done to at least two redditors so far: spaceedge and theronin23.

Joe Cumia states that he believes he can DMCA any material regardless of who owns it (because it's copyrighted by someone even if it's not by him) and implies he's DMCAing material he doesn't have the rights to:

[There’s nothing false or illegal about the DMCA’s that I’ve filed. All Photos and videos on the internet were taken by someone, therefore someone owns the copyright to every last one of those photos and videos.](reddit.com/r/WatchRedditDie/comments/d0hm71/reddit_legal_has_been_lazily_approving_false_dmca/ez9ze1y/)

Joe Cumia has doxxed and threatened to dox redditors.

Joe Cumia admits on Twitter he's Doxxer100

As username Doxxer100:

["I won’t outright dox you here, that’d be too easy, just want to let everyone here know that if it weren’t for your rich Mommy and Daddy paying your way, you’d be composing artisan sandwiches at Panera with the rest of your constituents. Moving forward, I’d pretty much watch what you say here."](reddit.com/r/OpieandAnthonyxyz/comments/cn54i9/my_sister_works_with_boc_srs/ew8knnf/)

.

["From the sound of his voice, He’d die from fear before I ever laid a hand on him. I’d like to Dox him just for fun. Stand gave to face with him and see what kind of a back peddling cunt he really is. All pussies..."](reddit.com/r/opienanthony/comments/bqsrw1/im_going_to_start_a_new_trend_that_will_be_very/eo8gi1r/)

Joe posts video as u/IntlectualHomosexual confirming his identity.

As username IntlectualHomosexual (which was banned for doxxing u/spaceedge):

Joe Cumia doxxed the moderator of OpieandAnthony soon after threatening to do so, causing him to shut down the sub:

["Yes!! Everyone keep shitting on SpaceEdge!! I could Dox him tomorrow. I've had his personal info for years. Would it be against Reddit rules if I create a throw away and did it? Then again, maybe the faggot will get sick of the abuse and shut this place down. Mod in the barrel, It's a GREAT TIME to be alive for all of you racist wife beating pedophiles."](reddit.com/r/opieandanthony/comments/bddbcy/thank_you_porsalin_for_legitimizing_the_fatrick/ekxl4mn/)

As username TargetedHarassment:

In response a question about what happened to the opieandanthony subreddit, Joe Cumia explains it was shut down after he doxxed the moderator and threatens to dox more redditors:

["Dox'd. More rounds in the chamber. Safety is on. For now."](reddit.com/r/opienanthony/comments/bg2ejc/what_the_fuck_happened_to_the_old_sub/elhvqfe/)

Joe references his doxxing of the opieandanthony subreddit moderator:

["Reading this thread, why so obtuse gentlemen? Just admit that without this Bovine brained, fat, talentless, lazy dolt, you WOULDN'T EXIST AS A SUB. No O&A, No you. AT ALL. That's a fact morons. As well, without my dox of TA the Mod, that other sub would at this moment still be engaging in the same mundane, boring-ass shit that it's been doing for the past few years. I'd been lurking there for a few weeks and it was a fucking BORE FEST. You can Fuck with me all you like, but you can not rebuke the facts stated above. As far as mod powers go, I know it was a goof, but it was fucking hilarious."](reddit.com/r/opienanthony/comments/bf85mf/do_not_give_joe_mod_powers_ever_again/elch5wv/)

Joe believed redditor u/theronin23 got one of his gigs canceled after u/theronin23 sent the venue information about Joe's political views and informed them that Joe had interviewed former KKK leader David Duke on his rightwing podcast.

On Twitter Joe offers money to doxx redditor u/theronin23, Josh Fonner and threatens to beat him up.

Joe harassed theronin23 on Facebook resulting in a temporary suspention.

In a tweet Joe Cumia would later say he had Fonner's "entire life on his hard drive." He somehow obtained nude photos of Fonner.

Joe Cumia would later post a nude photo of the now deceased redditor Josh Fonner on reddit.

Joe Cumia has threatened other redditors on his Twitter:

"Any IT friendly's? Get me a positive ID on 1 of these li'l boys? Find 1 $, I pay him a visit,the rest will shut up."

Tweeting about the same redditor:

"Not looking to beat them, just looking to beat one of them up."

Joe threatens another redditor on twitter, who he would later DMCA strike:

"D.R., You’d best avoid ever being in my presence at all cost. That’s all I’ll say. Go back on your meds for your own sake. You’re a lying sack of shit who needs to be corrected, and permanently institutionalized. For your own sake."

Joe says he'd wind up in prison if he were able to identify his online enemies:

"It most certainly is devine providence that I’m incapable of finding the owners of some twitter accounts. I’d surely be seriously incarcerated by now if I ever had their street address. This is not exaggeration or meant to be comical. #LuckyYouLuckierMe"
