Out of all the ICQ numbers in cyberspace, you had to walk into this one..

For the last couple of months I've been receiving millions of messages from random ICQ users. It's *really* annoying.
Why has it only started fairly recently? I've been using ICQ for years without getting random messages.

Anyway, I was wondering how ICQ.com's "Find someone to chat to" works, so went in, and searched for 20-something Males in London..
Somewhat scarily, it randomly presented me with... Zac. My housemate. (Who, incidentally, I think I only had on MSN before, not ICQ.)

What are the chances?
