why do you open your mysql port to the world?

if you want to let users in from any place, then an ssh tunnel is safer 
(yes, works even on windows, using putty or whatever. and a user who 
finds this difficult shouldn't be able to run sql commands!).

If this is too much, at least use a different port to reduce the noise 
(This won't add security, but will somehow limit exposure).
