(Paraphrased) "Why do I want to join a new web site that has been peppering me with invites?"
Social networking adepts understand that any web site that bugs you too much about one thing, will probably annoy you in other ways as well.
A few things need some light.
Q: Why are you getting tons of opt-in requests from your friends who should know better than to bulk invite people not already on a system?
A: Spock has pages for nearly everyone who has ever existed. When you first log in to Spock it, like most sites, mines your email accounts and asks who you'd like to add that "already has a page on Spock." But I had three pages on Spock before I ever logged on - Spock had crawled my business site, my blog, and my page on LinkedIn and created pages for me.
Then why my friends logged in, Spock told them I was already there - and THEN invited me. My friends thought they were connecting to me in a system I had already opted-in for - but I had not.
I made this same "mistake". So, Spock misrepresents their membership when you first log in.
Q: Why is this a problem?
When you go to an unowned page, it does tell you that the page is unclaimed. Going to an actual page comes long after the "link to friends" process.
This information harvesting has caused me work in cleaning up the Evil Spock database. It has caused me some embarrassment by inviting people to a service I don't think they need or will use.
But now, I feel compelled to tell everyone I know to JOIN SPOCK - simply so they can clean up their bios.
That is Evil.
UPDATE: No, no wait! They are even EVILER!
