Wix profiles.
If they click on a link that is in the Wix area, it doesn't have a redirection link.

also, tinyurl it.

"Buying with xxxxx gold" forums often ask for a link or will click the link if you post it right.

add random people and meebo it to them.

set up a seperate laptop or computer with a different IP address, use it to make profiles and use that to spread the link.

Use a proxy and make a lot of accts, keep using proxy to spread link.
