Hopefully Nexon catches this quick.

They hellbanned everyone who received hacked mesos from FM sales with the original donation hack for weeks, fucked up the quests and skills when they unhellbanned, took the hacked meso and never gave the items back either, Nexon are quite happy to adopt a scattergun approach with bans and then ignore you via feedback afterwards.

Oh well at least it solves the problem...
Then again, closing MS completely forever would also solve the problem.
