The same thing just happened to me today. (I had not seen this discussion until now.) I had just loaded my Wired Plastic account and came home to find it locked. The phone rep said that on-line gambling transactions had been noticed on my account, so they temporarily locked it in order to get me to call so they could me that these transactions were not allowed.
They reactivated my account, but now I'm very paranoid about using it for gaming transactions (which is really the only reason to have it.) I have a partial payroll direct deposit to my Wired Plastic account, so it would be an enormous hassel if they close my account completely before I can get that changed (which I will certainly do ASAP!)
I'm not sure which transactions were flagged... The vast majority of my gaming deposits are with Intertops, but I have made frequent deposits there with my Wired Plastic card for years and never had a problem.
For now, I am using my Wired Plastic account to fund my Quicktender account. Even that makes me nervous, though... my actual bank will not allow me to fund Quicktender from my debit card.
I do have a Netspend card, although I have never used it. I guess I will try that and/or the new Alertpay option and, if successful, drop my WP account entirely after I remove the direct deposit. Wired Plastic lost much of its usefulness to me anyway when they stopped accepting International Wire Transfers, which was always my favorite withdrawal method in the past.
