The chances of getting a patch for JTCS to prevent this are extremely remote since JTCS is no longer supported.
I did a quick test of this this morning in CSME and it appears to be true. I sent the file to Jason so he can confirm.
However, with that being said this is not the only way one can cheat. There are most likely other ways, perhaps many, out there that I or a lot of players are not privy too.
Finally where is the fun in cheating?
One only cheats himself when one goes down that road!
IMO once someone is caught at cheating I will never give them a game again. Just saying.
