oh and btw TP u can also casually mention that the crashers are suspected multiple acct cheaters. stars investigates any suspected accts by default and if they find any impropriety they freeze them and seize any $$ in them.
best way to deter crashers-threaten them with acct closure. they wont be able to siphon off all the ill-gotten coins away from all their multiple accts on time before theyre busted by stars support.
