EA has never explicitly said that handing out Origin bans alongside forum bans was its modus operandi; however, RPS finally received an official statement on the bans from EA Corporate Communications' John Reseburg. According to him, "when someone violates our Terms of Service, we are forced to take actions that can include suspensions and other measures." That's not a clear confirmation of the policy, though Reseburg later added, "We have listened to our customers and are planning a policy update which will include more equitable rules on suspensions – we want to make sure the time fits the crime."
It seems utterly bizarre that EA wouldn't be explicitly clear about a policy that carries as heavy a punishment as this. We can understand wanting to keep a forum free from the blight of obscenity, but if that comes at the cost of preventing legitimate purchasers of EA's products from accessing said games, those purchasers deserve to know about it ahead of time. As it stands now, Reseburg simply suggests, "any user with a question about suspensions or our policies to please contact us at (866) 543-5435 so we can address their specific situation."
