Since people are going to deliberately drag me into this shit again, I will look into it.
(TL;DR: 29-year-old Sam had sex with 16-year-old Marky Thompson and filmed her.)
Marky's birthday is July, 1997. Turns
18 in July, 2015 and was
16 in July, 2013. Sam is almost exactly 12 years older than her, so if they met when she's 18 he's still 30, which is still fucking creepy and weird but I will assume for the sake of argument absolutely nobody gives a shit unless she's under 16 (legal in Mass and RI). For the sake of argument I will also assume nobody has any contention they actually had sex considering there's a picture of her naked with him and I've never seen anyone MDE adjacent even argue they didn't, even Sam in talks with Soph.
Mentions of her being "Arwen-chan" and Marky on /r9k/ exist all the way back to 2013, that I can find, when she would be 16. I've seen some comments that she was active on 4chan as young as 13. On /r9k/ you had a few teen girls who had weird cults around them. I would call this a 4chan /r9k/ version of the Idol industry. Marky was one of these /r9k/ idols.
In particular, there's a thread on /g/ from 2013 of a guy trying to figure out how to scrub EXIF data because he apparently saw something about Marky and it made him afraid he'd get arrested.
All of the Channing schizoposting on every board of 4chan started late 2016, when she would be 18 going on 19. Channing told me that she was around for years before the schizoposting and she knew of this relationship when Marky was underage, but I don't believe anything she says and nobody else does either.
Coincidentally, all the posts talking about Sam and Marky are around late 2016 as well, which makes me think Channing is the one who broke it as news. This absolutely pegs that Sam and Marky had broken up by Oct 2016 at the absolute latest.
Boston Ross was January 2016. She would be 18 if this is for sure about her, which it sounds like it is. I've heard this was filmed 2 months before it was uploaded, but she would still be 18.
So at absolute maximum Sam and Marky were a thing by the time she was 18. We can also assume that's the absolute maximum because Sam in Boston Ross looks different than the Sam with Marky.

Sam's hair remained bleached on November 2016, after Channing began posting about Marky.
On November 30th, 2014 (Marky is 17.5) all of the videos of MDE1 are reuploade to MDE2. I cannot easily date anything older than this. Other people have tried.
Sam bleached his hair before November 2014, and Sam stopped wearing the red beanie he's in with Marky before November 2014.

I'm very convinced Sam had sex with an underage girl, who had been sexually active on 4chan (and was probably a fan of his) prior to that.
Nobody's really going to care unless she's significantly underage (<16), but I can't really verify that with the time I'm willing to take into this. But some other autist did.
Unfortunately, this guy looks and talks and dresses like the world's biggest retard. So, like Channing, he took this girl's story of being exploited as a young teen by someone she looked up to who was late twenties, and made it another thing to dismiss as bullshit from schizos and redditors.
From his video:
His "Sam Hyde Appearance Timeline" does what I didn't want to do and lines up his glasses, the red beanie, and the hair. He goes blonde one month after Marky's 16th birthday.
The autist deduces the picture is from June 2014, based on the glasses he wears with Marky being broken in a video uploaded at this date. Glasses can't unbreak, so this dates it as right before her 17th birthday.
This aligns with claims by Marky in private that she was 16.
16 is the Age of Consent in both Rhode Island and Massachusetts. The Marky picture is 100% from Mass.
- There is an argument that transporting a minor over state lines for sex is a federal issue, but I don't think any of Sam's fans would care about that so I won't explore it further.
- There's another argument that Mass. has a very weird AoC law that AoC is 16 unless the girl is a virgin, which Marky claims she was, but again I don't think any fan of Sam would care so I won't dwell on it further.
28 years / 2 + 7 = 21, so it doesn't hold up to my standard for what is ethical. A 28-year-old man should not be hooking up with 16-year-olds. But, I'd wager most people who are superfans of Sam agree that menstruation decide viability, not anything gay or soy like "maturity" (mature is a porn tag for older women

), so my opinion doesn't matter.
It's also very clear from her messages that Marky feels like she was taken advantage of, but I don't think Sam's fans care what women think, so I won't dwell on it further. The message above in particular also really highlights how immature she is. It really reads like little girl wrote it and not a woman.
The only other thing I'll mention is that multiple people have claimed she was filmed. This would be federally considered CSAM. I also think most people would agree that filming someone as young as 16 doing sex acts is generally "not a good thing to do", but to play devil's advocate it never leaked so he might've deleted it at some point to avoid getting in trouble.
FINAL VERDICT
29-year-old Sam Hyde had sex with 16-year-old Marky Thompson and facilitated her transport across state lines to do so. He effectively used her for porn fantasies involving anal sex and dumped her after getting shit on his dick and not having those porn fantasies live up to expectations, filming her in the process. She was very hurt by this experience and felt used, but she is a woman so nobody cares. Absolutely nobody who likes Sam Hyde will like him less knowing he buttfucked a teenage girl and most will probably like him more, even the tradcaths who think sodomy is a sin. Marky appears to have been promiscuous online and involved in /r9k/ idol worship, so even fewer fans will see her as a victim of anything.
Extremely creepy, I would not trust him, but I don't think he's a pedophile.
