I got the answer for your case, about half an hour ago, where I was busy writing an essay. They found at least eight connected accounts. Seven actually accessed from the same device. I'd like to hear your rebuttal, and based on what the point of your rebuttal is, I'll ask their supporting evidence to disprove the rebuttal.
This simply is not true. I have 1 account there and that is all. I have even just checked every email address i have and i have never ever had more than 1 account.
Also, why have they not communicated this with me? Why have they been purposely ignoring me for several weeks?
I reiterate, what they say is simply not true.
