That blows.lol I've never used speed hacks because i see them as pretty much pointless, sure you can get around faster, and no need for chocobo... But as of trying to beat the crowd to an NM or HNM i'm pretty sure people would notice and start spamming GM calls, probably even ppl in my LS ^^; But i have gotten one of my accounts banned before but it was pretty much on purpose, i repeatidly brought mobs in WRon to gate which in turn would aggro the low lvls sitting around wating for a toro to die. (just cuz i wanted to see GM Jail, never been there before =D) anyways a bunch of high lvls GM Called me (on my mule) and i was being nice when i got warped, told them i was doing it to see GM Jail and that didn't make them very happy

but anyways it was banned for 72 hours and i was being a smartass.
Normally GM's have a rating on each charachter, as low risk, medium risk,
and high risk of violating the terms of agreement. Past infractions with the
TOS can cause a raise in lvl of your account, and this can be done so without
your knowledge, so the fact that you were automatically banned could
be because you were giving him a hard time, and it might have been because
the GM was a girl and she was on the rag that day, but it's also very possible
you have had previous complaints on you account and you didn't know about it.
Anyways i'm sorry for your loss ; ; take it easy.
