I think bpip shoes nuked ban and autoban. It cant show any other ban, correct me if I am wrong in this point.
Edit:
Usually, ban occur for a full profile from posting and sending a message. But you have been banned for 2 years on the signature? What you have worn on your signature. I think you have been banned for your worn signature where you wrote something which broke the rule of signature space.

I can't agree with you. Most of the posts are one sentence. S/he became legendary only as he was an old member. I do not think s/he has contributed anything according to his/her rank.
