The writing style does not seem like Tera..... I suppose that the account may have been sold? She can report that, and maybe admins will freeze usage account? but if they have no way of verifying who is the real Tera, then they might let it keep operating with the new owner... then we might get a publicly displayed battle between Tera and Tera2, perhaps?
Perhaps some DT members would flag the Tera account if admins won't recover it.
