ye, with !b <weapon or item> on you activate autobuy and automatically buy this every time you spawn.
Maybe this is what made you think that.
Technically there is no feature that reduces your money except you buy something. There is no such thing as a stealing feature.
Very high admins could reset your money as a punishment or bcs there was an update to the mod and database, but i dont think this is what happened...
EDIT: thread topic "A question", are you serious?? Try to be a bit more creative next time ^^
