Very suspicious play on SWC (felt cheated)

Some small background, I've played a ton of poker both live and online, and mostly all mix games for the last few years. I consider myself a very good 2-7 player. My friend who also plays on seals is also an excellent deuce player who plays very large.

I started playing on the new seals about as soon as it opened and did quite well, the 2-7 games were so good they were very hard to lose. I had a few big losses to people playing quite absurd but that happens. However, I played a session vs player in question heads up deuce at 40-80 or 60-120 and he absolutely crushed me. It felt very strange though, like he could see my cards. Basically he just owned my life in every 1-1 spot on the end in absurd situations. I catch and Ace, he "value bet" a King, every time I made top pair he would check call or check raise in 1-1 spots, and he had absurd aggression leading up to the river. Stuff that would make absolutely no sense unless you could murder your opponent.

Without going into to much details, he was the worst person I've ever played in heads up deuce and he crushed me, I couldn't wait to play him the next day. Later that night my friend texted me that he just got murdered by the same player in the most bizarre fashion and that it seemed like he could see his cards.
I found this highly suspicious as we both think the exact same thing in the same day about the same player.
A few hands for background, twice my friend bluffed the river in 2-7 with a pair of 8s and got called by a pair of 6s and a pair of 7s. That makes the pot ripper 9-10 call look standard. Other times he would fold in 1-1 spots. How can you fold in a 1-1 spot and call with 66. Anyways we text back and forth and I kept saying call me crazy but I think he's cheating me and I won't play him anymore.

The next day we are in a 6 handed deuce game and same player is just going off, 3 betting in absurd spots and playing with crazy aggression, basically raising whenever given the chance.... until I open UTG he 3 bet, I take 2 he takes 1, I check he bets and I call, I take 2 he takes 1. I check and he checks back the 2-1 spot (any decent player bets here 100% of the time so I'd expect a crazy aggressive player to never check), surprisingly I drew 2 to the wheel and he folds the river..... a few hands later he opens UTG and I call in the BB. I take 3 he takes 1. I improve to 2357 and check, he checks back the 3-1 spot......

At this point I texted most people I knew and said be cautious playing him despite being awful. Fast forward a few days later and I sit in a PLO game were unpromted the text in chat was about how this guy got murdered by the same player the previous day and it felt like he could see his cards...

At this point, I felt like I was getting cheated but it could easily just be a fish on a heater in a high variance game so I would just quit him and let it go; However, he was also the highest volume player on the site every single week and all of a sudden he disappeared off the weekly leaderboard which I found odd. Recently a different friend emailed the site about the player in question with suspicions that he was charting somehow. They responded "as to the reason you don’t see player in question we can’t go into details but were aware of the situation and its not because he was challenged in chat... we can't share results of investigations....
we are very viligent about all forms of cheating, please rest assured......

This is extremely worrisome as well given the site basically has no rules and is anonymous so it would be very hard to be banned for anything other than maybe having 2 accounts and playing at the same time, but most of his play was heads up.

Lastly, I really hope they can divulge some info because I won't play there until I know more information. They banned him for something, but he can easily continue to play on the site since you can easily have and fund infinite accounts.

Hopefully I'm just overly paranoid about a fish running like a god vs everyone and then randomly getting banned for some random reason, but I felt like I would share this information.
