I didn't look into it very much back then. They were giving free hosting and subdomains back when such a thing was expensive and jumped on it for my homepage. Somehow I saw the Google cache of my page and it was surrounded by ads.

So they were serving different content to different clients based on user agent and/or IP block.

When I found out I deleted my account.

I see the site still exists, they might do the same thing. It's 3x on the .ro TLD.
