His profile is https://bpip.org/profile.aspx?p=riosakamoto in case you didn't see hyperlink.
looked at a few of his posts, he is not a shit-poster in fact the quality of his posts is not bad at all. and he didn't seem like a copy-paste person, i am interested in knowing the ban reason
. Well, if you are curious, you can start going through his posts and goggling them to verify none are copy/paste. I poked around a little. However, I'm not very proficient at it. I suspect other people have better tools to find these things. I already checked the OPs posted eth address and can't find any other accounts linked that way, so it wasn't for ban evasion.
