If you are aware of anyone who just walks away and you think they should be allowed to return, you should encourage them to appeal their ban with reasons to why returning would benefit the forum.
I really did not want to go down this road, so I will leave it at this:
They were banned for plagiarism for several things for several years, from many places. The issue is that it was *their* work. Proving that would reveal:
1) Their real name.
2) Their real job.
3) 90% of their home address, 99.9999% of their work address.
4) Where they went to school.
So, he walks away.
His choice. Not going to get into it.
