Unwanted Pm's, how do you deal with them?

[borbole]

I have been getting several unwanted pm lately to the point where it is getting very irritating. All of them are how can I do this or can you code that for me etc etc of this kind.

At first I placed that notice in my signature about providing paid support only in private and that seems to have worked for the most part. But I still get unwanted pm's and when I politely inform them that I charge for my time in providing support in private, they are like: Are you serious? Or Are you crazy dude? Why can''t you do it for free and all that crap. At first I try to ignore them but it has become very annoying and extremely irritating how some people are so selfish and don''t care about others as long as they get what they want. It is getting to the point where you do not dare to post the solution to someone 's problem because you fear you will get that unwanted/unwelcome pm.

Has anyone else from your guys received unwanted pm's of this kind and how are you dealing with it? Thanks in advance for your answers and thoughts on this.
