It's because you pushing one of those stupid free iPod or tv pyramid schemes that leech off of idiots. Want an iPod? Go buy one
. While some people have been getting their "free" iPod it requires the suckers that you signed to sign up and pay for some stupid offer. There are many complaints of these people not getting refunds for cancelled services and getting spammed to no end.
So there it is. You put ther referral URL in your sig and now you're on the list. Just to make sure everyone sees your punishment I'll add as my "friends" people with really, really long friend's lists. Look for the red/green icon by your name.
Lists are reviewed once a month and those that repent will be removed.
Now go away and stop advertising your pyramid schemes!
