Orkut Spam Stopper

Today I noticed a new way that orkut has introduced (when ?) to stop spraps (Spam + Scraps).

we're sorry, but you must wait 713 more minute(s) before you can post another scrap to this scrapbook because you have posted other scraps too recently.

Other method that orkut was using before was image verification feature when a scrap had a link.

If orkut is planning to stop someone for 713 minutes then what will happen to their "organic growth" ??

We do not actively review content that users post on orkut. As you can imagine, it would be nearly impossible keeping up with all the new photos, community posts, and changes to user profiles. Additionally, reviewing newly written posts, photos and profiles would dampen the organic growth essential to any social network.
