Truthfully I don't like any of the negative feedbacks left for this user as they are unreferenced and it seems like they are punishment for being disruptive and a general pain in the ass. Whether or not that renders them "untrustworthy" is a somewhat subjective call. And as you pointed out they were indeed accused of value betting (in addition to arb betting, which uh, well they should have stuck with one or the other), so the feedback left against them isn't totally incorrect.
got it all confused.
I was talking about you in the above quote, actually.
As far as OP's case is concerned, they should just pay out the winnings of all the bets & then close their account. They haven't been around for very long and therefore there isn't a lot of talk about them on the internet. The forum being the SEO powerhouse that it is will show up on the first page of search results for this casino, and their behavior might be off-putting to some. So its in the casino's best interest to just pay out the winnings, IMHO.
That's the last I have to say about it.
