1) Someone buys the name for 100m
2) They put membership on it and change the name to something random like Mr Lucky X (which was the previous name)
3) Everything is all good until BOOM, the account gets locked.
4) The buyer writes an email to Jagex; they cant help the buyer because they are not the orignial owner of the account
5) Finally, the owner gets back the account, waits until he can change the name back to red
6) The name is up for sale on Sythe again! Ta-da!
