I have to agree that there needs to be some kind of mechanism for dealing with cheats. I honestly can't remember the last time someone was taken to task for it around here, though maybe I missed it, but it seems like a no-brainer to have some kind of MO in place.
I would also agree. Although, the fact that this has been left unspoken about for some time makes it extremely hard to try and prove - while the person isn't active right now, if this had been brought up back when these were being posted then they could've been confronted then and there. But, because they are currently not around, trying to get them to livestream or play PvP is out of the question, so all we have to go on are it-looks-like's and it-could-be's. It's quite difficult to point out a submission is cheated too soon after it's posted in any case, no one is, and I doubt ever will, consistently check every new posted score.
I'll personally watch the replays tonight and say what I can see. However, "it looks like they might have cheated" isn't really grounds for removal of scores, unless it is blindingly obvious. And I mean frame-by-frame obvious.
Currently the only mechanism in place for dealing with cheats is removal of scores and not being allowed to submit again, but I'll discuss Random's replays with some others and see what they think too.
For future reference, if anyone thinks that someone may have cheated feel free to PM me either on here or on IRC, you can find me on #ijiyatsu on irc.ppirc.net or #pc-99 on irc.rizon.net.
EDIT: If anyone would like to highlight replays / stages where it is most obvious, please do so.
