I'm not really in support for the ban for users who are above Hero+ and have 1 or maximum 2 posts copy-pasted. Like in terms of signature gains, how much they would have made copying the two posts? If the posts are from 2017 and less then they should be given another chance instead of a perma-ban. It's sad to see a legendary member getting banned for copying one post in 2016.
Unfortunately, Hero+ accounts sell for a premium, so people can get in good sig campaigns and sling their sig all over the place. Also, I'm not sure that we can expect a moderator to sift through an account's post history to see what the extent of the plagiarism truly is. I suspect that tvplus may have other copy paste posts, since suchmoon exposed that he was prone to copy/paste a quick answer. Also, I believe suchmoon revealed that with the tools that she uses, searching through a post history is much more difficult than just going through a shitty megathread and finding hits.
