Hey, Someone has created a greasemonkey script for mass scrapping on Orkut. Check it out:
http://tech-buzz.net/2007/01/19/how-to-send-mass-scraps-in-orkut/

What's a scrap and why is it useful?

great to spam people...

<< Scrapping is a way of messaging another Orkut user, by leaving a public 'scrap' to that user. >>

Like in a guestbook?

Why do they have to give a name to everything, to confuse people even more? It's quite simply a COMMENT.

Ok, that blog post says it will only send scraps to your friends. If this is true, then unless you made friends with a spammer you ought to be safe.

Do you use Orkut ?

I think a guestbook is a little different

Here's where the confusion comes from:
Facebook – Graffiti? (It doesn't have a name, but it is writing on someone's "wall")
Orkut – Scrap
Myspace, Blogs – Comment

I can´t login into Orkut today, what a piece of crap.
