I’ve blocked 60 apparently - about half are people from my past that I have no desire to have any contact with again, others are spammers, weirdos that PM’d trying to hit on me, people I got into disagreements with on Facebook groups and decided life was too short to argue with, and the rest I don’t even remember who they are or why I hit “block” 
What about you?
If you go to Redirecting... it should show you a list of who you’ve blocked. But not why 
Everybody (so far at least).
How long did it take you to create an account and add all seven billion people in the world to your blocked users list (give or take a few for those with multiple accounts, and those with no internet access)?
None. Yet.
Two for me. One is a former co-worker, and I have no idea why I blocked her. I don’t remember adding her as a friend or blocking her. The other is an acquaintance who sent me some annoying messages.
How does blocking compare to unfriending?
Zero. I don’t have anyone on ignore here either for that matter.
If you unfriend someone, you can still send them PMs and if you both comment on a mutual friends post, you’ll see each others comments and can chat there.
If you block someone, it’s like they’re not even on FB anymore. You won’t see their name when you search, you can’t private message them, and you might just see odd one-sided conversations on a mutal friends status with things like “Yeah, Susan’s right!” when you’d never seen any replies by Susan to that post.
Thanks!
Blocking a person means they can’t message you, search you, see friend-of-friend posts, or otherwise find you or bother you at all. If they log out they can see what’s public on your profile, but that is it (and you should not have anything public anyway). An unfriended person can send you messages, find you in search results, try to re-friend you, and see friend-of-friend items as your security settings permit. You can of course tighten down your security settings but you’ll never get an unfriended person down to the same level of “nope” as a blocked person.
I have one person blocked for being a creep.
Two. One of them I have no idea who it is. The other is an acquaintance from elementary school who’s just as obnoxious as an adult as he was back then, so I was kind of subconsciously looking for an excuse to cut him off, and then in a thread about Obama he made a spearchucker joke, and I was all, “nope nope nope” and that was it.
Just one - my sister.
She only realized it fairly recently (her narcissism is only one of my many issues with her) and immediately posted something about it on her wall (her victim mentality and endless need for people to feel sorry for her is yet another of my issues). I ignored it. I noticed a marked cooling from extended family after that, but that’s fine (her ability to manipulate people also makes the list). Life is too short for family drama. 
Oooh, good one. I apparently have three on ignore here (http://boards.straightdope.com/sdmb/profile.php?do=ignorelist) although rules prevent me from saying who they are, outwith the Pit!
… how do you know what she posted on her wall, if you’d blocked her? Or did interfering family tell you what she said 
None for me. I have a small FB circle, and luckily no one has bothered me enough to block them. I stopped following one guy. He’s still a friend, but I got tired of seeing his unhinged posts, so I just set it so I wouldn’t see them anymore. I don’t mind exchanging notes with him here and there, I just didn’t want to see his daily stream of consciousness. Otherwise, I just have I think 20 friends, and they all seem well behaved enough.
Got it in one! My response? “Oh, huh.” <change the subject>
I told you I wanted to send you a bunch of nice PANSIES.
One typo and your damned forever
Every time there’s some big societal tipping point I’m amazed I haven’t blocked more people. Like the ones who I’m pretty sure think we’re going to forget about the troops if we talking about Catilyn Jenner for more than a day and a half.
None. I had one person on ignore for a bit, but I stopped that a while ago.
Holy shit. How many “friends” do you have on facebook?
I mean 60 people blocked, wtf.
I’ve never blocked someone and nobody has ever blocked me back when I used it.
I’ve blocked nobody.
There are a few who I’ve quit following for various reasons like most of their posts are centered around family issues that I have no interest to my friends who think that FB is the perfect place to tell you how horrible the Dems, Pubs, Conservatives, Liberals, President are.
