"Tons of posts" is a huge stretch. Again, I've followed this guy for years. He's a huge sports betting geek. I'm sure some of his posts are about KYC, but the vast majority are general sports betting stuff: puzzles, sports betting philosophy, lines that he is interested in, tickets that he cashed, comments about business models of particular sports books, player disputes, his FanDuel account getting hacked, BetBash...
In September he made a tweet suggesting he's part of a syndicate ("If you are working as part of a team in sports betting, Google Drive is amazing."). Frankly, it would surprise me if rolandcort's rumor were true.
