Come on. I've seen hero river calls like this before that had nothing do do with "superuser" accounts . The famous texaslimitking one was mentioned already and recently Negreanu vs Stinger has been posted, and srugby mentioned one vs. him for $1m live.
More likely explanations:
1)potripper was simply a rich donk calling station
2)he wasn't paying attention
3)he misclicked
4)he's metagaming
5)he didn't want to be bullied
6)he had a big chip lead and could afford to take a chance to finish the match.

The Doubledrag data is based on a tiny sample from a high variance hyperagg player who simply ran hot. In the long run this type of play will lose tons.

If AP poker wanted to reward someone they could write them check or another hundred ways better than jeopardizing their entire business with a "superuser" account.
