So you are already evading ban even after getting banished out of the forum... thanks for bringing yourself to the attention of the authorities. You just earned a ban for this account too
25. If you get banned (temporarily or permanently) and create a new account to continue posting / sending PMs, it's considered ban evasion. The only exception is creating a thread in Meta about your ban.
I have never seen anyone get banned for merit abuse. The abusers just get their accounts negative trusted. I am very sure your case was either plagiarism or spamming.
