Facebook security check, but why?

[Major]

Hello all,

Yesterday was Halloween, I saw some interesting halloween cosplay/dressups on my news feed, the most interesting being a couple dressed as the Adams family(dead people). I copied the image URL and sent it to a friend via inbox to share this amazing idea for a Halloween dressup. Llater it said I had 'no permission to send this image'.

I later 'LIKED' the photo so my friend could see on his newsfeed, that was blocked also, I had to complete a security check, naming people in photos immediately after i liked the picture.

Why did facebook make me do this, why was I blocked from Liking/coping image url of a picture ?
I am a university student, so above the age of 18
Im british

yesterday wasnt halloween ! today is halloween day.

okay, i gotta tell you something you should had heard ? if you have facebook account and your under age children between ages 10-17 still in school or is a teenager year? then facebook has made a new rules and had changed the tool that no children that is not a adult age can not write on any of their friends comments boxes and on their walls anymore. the facebook team put on the blocker app on the only for the kids who are under ages that has facebook accounts. the reason why that did that only for the teenagers because they found out that many of the high schools students had made a big no no bad stuffs about other kids who has been getting bullying from their classmaties or anyone who is on their friends lists or on other friends by friends and made alot of problems when they are on there? there is a news about it on Yahoo news homepage where you can go check it and read it why the facebook did it. and they also trying to keep help children out there not make any more trouble. so only for the adults who has facebook is more alike not making any hassarening / bullying to any younger people on there. most like alot of highschools kids making troubles on their facebook timeline.. so iam just letting you know what has changed on facebook. that must reason why your friends cant accept the stuffs you had post onto their walls. because facebook must had blocked the inks and coping stuffs from users .

It's probably because Facebook thought you were someone who you weren't, someone reported you, or they thought you were sending spam to people. Facebook's security shit is useless.
