Participating in event broadcasts to get more items than intended:Remove all of the relevent items in their inventories, even ones got from the event in prior decades. If you mistreated the shiny easter egg buff event this season, then you deserve to have every one your buffs you've collected/hoarded over MS Mesos time deleted. If possible, this should be accompanied by blocking that participant's account from participating in the event if it comes back in the future.

Clearly some actions should still result in an immediate ban. Hacking, using somebody else's buy Maplestory Mesos accounts, duping etc etc.. . But overall few actions should immediately warrant a ban, however they nevertheless merit a punishment. I truly do believe that this sort of system would cause a really positive shift in the way the community thinks about breaking the ToS. And finally, if you disincentivize them out of breaking the ToS at the first place, you then won't run into problems on precisely the same scale as the Shiny Easter Egg Buff exploit or hunters club pops. You may also, finally, have fewer gamers botting for levels.
