They need to hire more GM's or something and get them on those Reddit posts where players are selling plots and then get the GM's or whoever to buy plots from the players who are violating the ToS and then once the transaction is complete, ban them. That would help shut down those massive dedicated Reddit posts for selling housing. Players can also report other players for doing this, although I wouldn't recommend going through with a transaction and then reporting because I believe even buying is against ToS? If I'm mistaken on that please let me know. It's malicious intent regardless and shady.
