Well, I disagree. The basic mechanics are not in dispute i.e. 32red erroneously credited excess bonus which enabled the player to win. They also have a term to cover this.
The poll simply asks that given these circumstances at present, what people would consider a fair outcome. When the player spotted this is irrelevant as it simply can't be proven by him, 32red, us or anybody else and therefore can't have any influence on the poll question.
But it seems more complicated than this: the $2000 bonus also came with 35x wagering and it was therefore IMO no small effort to bring his balance up to $25K, taking into the account the fact that he had to wager $70K.
