Pirated Sites!! Aaarrgghh...
Pirated-Sites.com showcases side-by-side comparisons of web sites that are suspected of borrowing, copying or stealing copyright-protected content, design or code without permission.
Where do the comparisons come from?
Some of them are examples [I] run across during [my] day. Most of them are submitted by users, and about 50% of those are submitted by someone affiliated with the site being copied.
Do I need to be the owner of or affiliated with the victimized site to submit?
No. Anyone may submit. We review all submissions for authenticity and appropriateness prior to posting.
How is it wrong?
Oh, it's wrong in so many ways. Ethically, you are benefiting from someone else's work, without permission or due compensation. You are taking something that does not belong to you. Legally, you are violating that person's copyrights, and they may be able to sue you for infringement.
