I've got a question.
I really am starting to think Facebook went through my Gmail contacts without me even authorizing it to do so. In the past hour, it's suggested three people I
1) Don't have any friends in common with
2) Never searched for on Facebook
3) Never contacted other than through Gmail
and 4) never even worked with
One guy, I used to play Team Fortress Classic with, who only I've talked to through email showed up in my suggestions. Has anyone else experienced this?
- koenigdavidmj 17y agoI just noticed this when helping someone I know create an account. Many of her Yahoo contacts were recommended without it asking for a Yahoo login (Ironic, eh? Facebook calls that criminal when other companies do it.). It also found many of my friends whom she had never even heard of---I had even defriended a couple of them. I'm thinking that it's also recommending based on cookies/session or IP address---perhaps their logic is that a person living with me likely knows many of the people whom I know.
- kmavm 17y agoThe contact importer works both ways; so if A has emailed B, and A imports his contacts, A might get recommended to B as a friend. This is the usual explanation for mystery PYMK suggestions. That said, the algorithm for finding candidate pairs uses a lot of features, including past employers, schools in common, graph features other than just distance, etc. Occasionally it has a surprising success like this.
