Same happened to me. Saved up all my adena for months to over pay for an un-restored clean dragon earring. I submitted a ticket for it to be looked at to make sure it was indeed restorable. The GM ignored my initial question completely and told me I'm associated with an account that has restored something, a clan member that came to visit me some months ago. Even though I have all my tokens on all of my characters, I now have to wait until July to try and enchant this earring before I get associated with some random again.
Also, they let me know if I were to try and restore something in the future and someone else I'm "associated" with restores the same type of item, I will be denied any restorations in the future. UNfair, if I don't even know who I'm associated with and what they restored because its none of my business. Being someone that has only restored a few dyes my whole duration of playing this game, this is extremely unreasonable as there are few people who exploit who should deal with the consequences, not normal players. The policy should either be reverted to the old system, or there should be and option to claim what accounts are actually ours.
