Today's Suspension Toll
The suspensions stay the steady course, and it seems we can expect this trend to continue. If my leet Google Translate Skills are correct, today's suspension count was : 780 existing accounts and 16,512 new accounts. It appears as though they are now distinguishing between active accounts (probably for using macros, cheats, or code-modification), and brand-new ones (probably mass-created for the purpose of selling). A complete list of punished accounts can be found here.
Q: How can I find out what is bannable and not?
A: Yostar's Terms of Service can be found here.
Q: Is using an emulator a bannable offense?
Q: Is using macros for farming a bannable offense?
Q: Is having a second account (aka clue slave) a bannable offense?
A: Technically, yes, though personally I have doubts that they would ban you for a few extra accounts. Most likely their concerns are mass account creators who intend to sell. But keep in mind, it is technically bannable.
