GigaBlast?

I recently found the site GigaBlast which say it will help to exposure Your site.
Anyone got experience with that? Do anyone now it?

let me know please...looks interesting, but i fear of scum....

never got a visitor from there (blocked the bot because of massive crawl)

It seems to me that there just trying to get some massive backlinks
and they have actually succeeded
Yahoo shows about 182000 backlinks ...

yeah...i thought its suspicious...
now i know...thanks
