Q&A: What’s a good site to find any copyrighted web scripts?

Question by Mike Gambino II: What’s a good site to find any copyrighted web scripts?
I know a lot of people are making lots of scripts every day but there is a website that you submit all your codes to this website and they check to see if your scripts are copied by another scripting company or not. The reason why I’m asking this is because I’m building my own scripts that will be sold and before I release them, I want to show people that these scripts were not copied by anyone.

I also copyrighted these scripts but people keep on telling me that they won’t believe you created these scripts unless I show them proof that they were not copied by someone else.

Never heard of it. Your reputation is more important than a website to check it. I.e. you need people to trust that it is your own work. I cannot understand why they would not do that.
