You are not going tag-free unless some other trusted user can verify you for sure. Does that make sense yet? 
No, it does not make sense, every time a person loggs in after long time does not mean he is a hacker. Also, I don't think anyone could hack my accounts as I have set most of the security to my email. You cannot just tag peoples here without any proves and evidence of the case. This could be stated as power abuse in simple words. I have proves that I own the original email from start. Does that make sense? I understand, but still... did you have someone email you to prove it yet? I'm not abusing power, I just don't want to see anybody get scammed down the road.
