Why I can't add my site to the system?

Check up the following:
1. Have you created the folder containing our script?
2. Have you set the rights for the folder as 777?
3. Have you set the rights for the files within this folder as 666?
4. Have you added correctly the code of the link call to the pages of the site?
If you followed the instructions in your account correctly and the site still won't submit - contact our Support.

Is it possible for search engines to detect my site as the one selling/buying links?

No, it is impossible for search engines to detect your site as the one that's selling/buying links,
since our link marketplace does not leave marks in the pages' code after link placement.
