Is everyone on UB a hit and run artist?

[Teetster]

Here is my last hour.

1) Install UB.

2) Deposit

3) 2 Table $25 NL (LOL low stakes)

4) 2 minutes in: Lose KK < KJ for a buyin - villain hit and runs.

5) 5 minutes in: Lose 99 < 98 on 272 rainbow flop. Money went in on the flop. villain leaves next hand.

6) 10 minutes in turn but spade flush, bet pot, villain calls. River pairs board, push remaining $2 into $25 pot. villain obv had set and fills up. villain leaves next hand.

Is this standard for UB or what?
