I think game where Phill Hellmuth got the pot from Doubleballer with loosing cards is a major hall mark in the hall of fame of poker scams.
The facts as presented by 2+2 forum are clear.

I think they did admit and correct this.

Someone at 2+2 forum considered that it could be caused by malfunction of
inhouse users cheating software?

I check the story and the fact how they tried to change the story and blame just technical incidence is revealing.
After several other incidents came up it became minor computer problem which will be taken care of and won't eveer happen again.

I think that if such happens it is likely because of at least attempt to include "special effects" to the computer program.

The site has admitted the mistake and 36 others
in press release DECEMBER 23, 2008 - Tokwiro Enterprises

They are blaming computer mistake and Hellmuth was having "ton of trust in UB’s software and new management team."

They were looking for additional historical mistakes.

There is evolving Collision Scam revealed with 20 dollars game at Cereus by 2+2 forum.
With the background of this and Absolute Poker and Ultimate Bet,
it does not look good.

On twoplustwo discussion of Ultimate bet background major frauds were spammed.
The site has fanatic fans or they want to hide the constant history od oddities.
