I have reasons to believe the opposite, I expect the bot to stay up and running, busting plagiarizers indefinitely. The expenses needed for it to be online 24/7 seems to be secured. So fellas, fasten your seatbelts, there will be a shit ton of those ban appeal threads and maybe having a separate sub-board isn't the worst idea given how much they clog Meta.
Bot likely will be kept running, I believe, but over time, there will be less or no plagiarism made by higher rank users; and most of plagiarism-found users in the future come from lower rank users, especially newbies. I don't think Newbies will create Ban Appeals, they don't care about that. Does it make sense? In the past, there were suggestion to have sub-boards for merit, trust issues, but all of them went away and cooled down, ban appeals will follow the same pattern, in my opinion.
