I'm not sure if this has been said yet...
But that 1k was NOT free money. If it was credited to OPs account for the superuser incident, it was compensation for being cheated. That means that the money is the same as a deposit...this isn't a freeroll for OP.
And you should feel pretty comfortable with the 1k, seeing as how they must have reviewed your HHs...or...ya know...90% of them.
Seriously though, do not think of this lightly just because it was credit OP didn't know about. I think if you backlog a little further in the story, it sounds more shady...
1. UB cheats OP and poker world.
2. UB denies.
3. UB is caught.
4. OP leaves site that cheated him.
5. UB eventually refunds OP for being cheated, but refuses to offer the evidence to the poker community.
6. Yoink! That compensation for being cheated? Forget about it. You don't like us anyway.
Pretty disgusting tbh.
