no, I either have to ban everyone or wait for Simon who's been missing a month (but he said he'd be back at the end of this month, which is only 2 days left).

But I can say that whoever is doing it can expect a much longer ban if they don't come out an say it. If someone did admit to it and stopped now, I would probably ban them for a few days; but if they keep doing it secretly, maybe a week or 2, since that's how long it has been going on.
