As an aside, unlinkings are not just an iEra thing. When an account is unlinked, it means the email was disconnected from whatever graal account was associated with it. This means that if you get unlinked, your Ol' West account, Classic account, Zone account, and Era account (and whatever other servers there might be) associated with the email would all be affected. Because of this, unlink reasons may not have even occurred on iEra. It's a global thing, and iEra staff have nothing to do with it as far as I know. Whether or not the manager can help with unlinks, I honestly have no idea (because it's a global thing, not an iEra thing).
As of right now, I do know only one instance of someone getting their account relinked. And this was not done through toonslab, it was done through
[email protected] (that's a global email for general account issues not related to any server). From what the person told me, he emailed them multiple times spaced out between months trying to get his account back. He told me that to get the account back, he recalled a situation in which he mentioned that
certain other game and explained to them what was actually happening in the situation and what he thought was the reason he got unlinked. He defended himself and the situation was looked into, and ultimately he got his accounts back. Whether or not that has worked for anybody else, I really don't know.
