I create a website dedicated for gambling. Outlined within the ToS are a few clauses that allow me to arbitrarily freeze player balances, all fit under one nice long section. One of them is based on if I have suspicion that they are using multiple accounts or money laundering. Another is simply, if at my discretion, I determine that you or your account is detrimental to the conduct of my business. I use this to freeze player balances when they win. When questioned, I respond that they violated the ToS by stating that they violated the section containing those clauses. I do not provide any evidence and then state, "we'll return the deposit though."

Fair, or not fair?
