Honestly if I were them I'd power down onto a new account and try a different method next time since it seems they're too deep/stubborn to back out of anything now and on too many blacklists cause of what they attempted to do. Now you may say I'm giving them ideas but I'd rather they do something better with their stake than whatever they are doing now, they could be growing their own community/language users and attempt to see the bigger picture where giving means receiving instead of just attempting to maximize their stake like there's no tomorrow.
