I witnessed an 86 once in my life and
the guy was not a card counter. I know this for a FACT because I was gambling at the same table when security threw him out. This idiot was a big pain in the ass to the players as well as the pit. The jerk would consistently say he did not signal for a hit when he busted or place a bet close to his original bet and if he was dealt a winning hand he would tell the dealer he doubled down while the dealer was squaring up table bets. He also used many other verbal and annoying tactics,on one occasion when the dealer called for insurance, he placed what appeared to be a double down bet near the line. When the dealer flipped over the ace and began to take his money he shouted " Woe! What you be doing man, that's my insurance bet,ya know what I'm saying!?"
Needless to say after the pitboss made several (far too many) trips to the table over disputes, the drunk jackoff was finally 86'ed. I was relieved and content with the decision made by the pit, and NO I'm not a pit boss, anyone here who recognizes my handle can assure you this.
I'm not saying saying or implying you were 86'ed for cheating, but rather implying that not everyone should assume (I surely dont) that everybody who makes post on the internet about being barred does not mean they are professional high rolling card counters, this is often far from the truth.
