I don't know any dev that improved the Ghostrider algorithm because I am mining Raptoreum and the only dev that I know is the real one,who is also providing the binaries through the official Github through the Raptoreum official website.

Any smart dev that provides an "improved" version of this algorithm is most probably providing people malware and once it is known that it is malware getting him banned is the best thing to do in the forum so we can save some unsuspecting newbies by downloading this infected software.

If you can't give any specific details about the case, we can't give you any explanation or even an idea of what might have happened. The ban was what it was, and you have to move on. However, there are cases where a ban makes sense, and I can assure you that there is no personal vendetta against him or any other member. If you feel that a ban has been unjust, then the best way to remove it is to contact the staff or post about it on the Meta section. A staff members will review the situation and either remove the ban or explain why it was justified.  But please give us something more specific than just, "suspicion" and "concerns", because otherwise we won't really be able to do anything for you.

Maybe whoever you are talking about got caught in the ban wave where people were spamming malware 4x a day and it looked a lot like one of their posts.  Either way if its sus its getting banned, not that big of a deal.
