Autofriend 

The job of a script or program which automatically ads friends on social networking sites.

If there is one thing I find annoying about social network sites it's when some spamfriender script tries to autofriend me.

Antifriend 

A friend who lacks the qualities of an idealistic friend. Not to be confused with a frenemy which is more of a love/hate relationship. May have been a close friend at one point. In many ways they are fiercely independent or distant for personal reasons, which creates an air of tension. But, that tension is never redeemed, so they are especially prone to becoming the black sheep of a group.

We tried reconnecting as friends but it's not the same, I guess he's an antifriend now.

Autofriender 

Any system which automatically ads friends on a social network system. Similar or even identical to a spamfriender, but not so much about marketing as just conquest, ego or vanity.

That guy has no life at all. His idea of making friends is spending time in his Mom's basement writing autofriender scripts for his facebook page.
