Tip #1 "Tom" is not your friend. :)
You aren't the only one who has him (he's there by default),
GOOFIEST thing because "Tom" is networked to everyone through SOME friend, "everyone" is in your extended network.
Friendster had this feature first and would tell you how many immediate, second level, etc.. friends were in your network (friend of of friend associations; ie someone is identified as your friend and then sum up all of their unique friends that are not currently identified as your friend).
Friendster never had the "Col. Sanders" figurehead that Myspace does with "Tom".
So... One should block "Tom".
