I have placed 2 shareware application that were written in VB 6 up for sale on the internet. The application requires the user to send me their validation code and then I use that code to generate a registration code. I then send them the code and they type it in and it unlocks the program

Well, there is a group called "Silent Cracking Force" or SCF that has cracked both of my programs and put it on their web site. The web site is http://cracks.allseek.info/. If I was you and if you have written shareware, I would check this web site out and make sure you app is not on here.

Something has to be done to try and slow these guys down. I know it is pretty much impossible but there has to be a way.

If anyone finds that there app is being cracked by these guys then reply to this post. Also if you have any suggestions on what can be done then post that also?

Is it possible to sue for something like this? Is there any legal issues?

Something has to be done.
