Spamfriender 

Any automated system for auto adding friendships on social networking sites. Or a person who simply friends people he or she doesn't know for the sole purpose of increasing the size of the friends list.

thechurchofdave youtube channel finally stopped using the friends list because most requests are just coming from a spamfriender belonging to some get rich quick numbtard.
