Sorry man... if what you are telling me is correct... that you sent a score that is impossible due to mod... then yes... you will be banned. Sorry. May take a few days or a week... but they will catch it.
Next time try running on a shell and use proxy to clean up your list. Update the list every month. Never run the same list twice. Randomize... frequent stops and starts. Do not browse other stuff on neopets while running the program. Do not send money to your main until you sit on it for a few months.
I did run it on a shell and I used a proxy, but I sent the money to another shell a little while later (less than a day). What's the chance that they'll chain freeze?
