look at their policies, and u'll see that under "Bug Abuse" it says 30 day ban//account termination
u didnt get either of these although u ABUSED A BUG. no matter how stupid the bug is, or how less crucial of a bug than exp bugging, it is still the abuse of a bug. therefore, truthfully, u deserved to get a 30 day ban or some sort of punishment, but u didnt.
u should be glad that they didnt ban ur ass for a little bit, not angry that they took action and followed something that they said for once.
im glad that they did took these course of actions, otherwise, another set of people who abuse bugs move on to use the next one that comes out
