You can customize what people can see… and even by group or individuals.
I decline friend reqs from people I don't actually know somehow. It's not personal. I even decline reqs from people that I might belong to the same whatever with them (school, forum, etc) but don't really actually know. I have declined from people I do/did know and just don't want to be FB friends with… *shrug*
I find there's the people that treat it like a mash between real actual friends and networking… so those are the people I might know of, and kinda travel in the same circles with, but don't necessarily "know."
On the bright side, you can get to know people better that way and make more friendships. Depends on how you treat it.
I don't friend people too often, I usually just get reqs. I'm in no way offended if I do send one out and it gets ignored. Why should I? People treat what "friend" means differently and some people only are friends with their actual real life close friends and family (for a bit that was me even), or whatever… I mean, if you're that upset about something like that, I think you need to get over yourself.
And I have plenty of people who friend purge all the time… I'm sure I'm just overlooked that I'm still on their lists.
