IANAL, but depending on state law, running the poker games on your campus might be illegal (not a law I'd agree with, but possibly illegal).

In a regulated online poker scene in the US, botting would likely be illegal, just like using a computer to aid your play in a live casino is.

While I understand the value of rakeback and low rakes and poker sites not treating their customers poorly, I don't think it is relevant to whether creating a bunch of fake accounts to receive affiliate commission is okay.

Anyhow, seems like it's all in the past, so all of this shouldn't matter much.
