Is that site cheating or something?
As an honest member of the human population, I can tell you yes, there are cheaters at the Seals With Clubs tables. The nonchalant attitude they have towards fraudulent activity there is kind of startling.
I'd say I catch one about every other time I sit down at a table, but don't really know how to report them.
Here's what you should look out for:
-evidence of collusion (players working together, frequently playing at multiple tables together)
and
-1 player with multiple IDs (sometimes they are foolish enough to admit this is what they are doing)
