Never ever heard of her in any way, so maybe an alt. But this risk we have to take. Did you ask her at what times she is around? And if she wants to help at events or with dungeons? We need active US players, or at least from about the server time zone. Well, guess we have to find out. If she dont show up or find out later that she is an alt, we can kick her again. So yes if noone has other infos on her.
