The thing is, we have NO IDEA why these accounts were banned. I don't think it had anything to do with sending crystals to your alts. I think the collections system sent off a massive false positive on someone's exploit script. My husband's account was banned for a week. He payed money out the wazoo to have all his crystals and outfits account unlocked. He didn't mail anything to his alts as he didn't need to, he simply paid the CC for the account unlock on everything. The artifice exploit? He doesn't even have a toon with artifice over about 50 (he hates artifice). His reward for literally spending hundreds of dollars obtaining and binding rare items... A one week ban with no explanation. Thanks Bioware! Awesome service!
