I tried to check all the posts you refer to, but none of them are available on the forum anymore.
To get someone banned, It must be available on the forum. Moderators do not consider Post Scraping links like Loyce.club or Ninjastic.
This is not my statement. One of the Mods said that, but I cannot find the Post now.

Mr. Right Deleted all those posts before any moderator saw the plagiarism report.
So, He is safe now and don't expect to get him banned if no new on-forum plagiarism is found.
