I will begin running the Buddy Link spider, some time this weekend. User Agent will have "buddy links" in it for identification.
The spider will hit your links page and verify it is there. We just do a compare of links that are there and links that were generated when you signed up. This should keep the system honest. It will weed out those signing up just to get links (which has happened several times already).
Yes, you will be putting up a new page with 100 links in it. The pyramid part happens between the big gains in users. Such as those that signed up early, have their links on 28 pages as we speak, while those that signed up around 20, have theirs on 8. Just depends on how fast we grow.
I've been wrong a time or two before but I really believe this is the start of something big.
