Can you give us some more information about the ideas/products which your competitors have stold from you? Maybe if we have specific examples we will be able to help you more.
The thieves steal because they lack creativity and talent. What you must do is to be very fast in regards to contacting prospective clientele with original designs. So...speed and originality is the key to your success and their downfall.
Thanks spoiltdiva! One more question, what they do is collecting emails and send with low price the same design i designed so they want to show i am expensive any ideas?
End each of your e-mails with the following: In business one gets what one pays for. Good original designs deserve quality rates.
Get copyrights on your work and report to their provide about the copyright infringement. It's a tough fight cause they might take a new domain and start selling again.
It's a waste of time even worrying about it, if you're putting something online worthless scum are going to steal it no matter what you do.
You can definitely report them. If it's serious enough, they can be tracked to the source itself rather than a bunch of interchangeable domains.
