Well.. Dangerous is such a harsh word for it.. Unwise or ill-advised may be better. It's not something I would do to be honest.. I would change the pic.. Or download it, open in paint, erase/black out house number.. then re-upload it. The thing is.. People can see the main profile picture regardless of friend status.. And not only that .. profile pictures can de downloaded by anyone.
All your FB pictures can be downloaded by your friends. People have been known to scour someone's FB page to gain information.. For malicious actions such as burglary and other bad things. And unless you have changed your FB privacy settings.. Chances are ALOT of your personal info is available to anyone.
If you keep a tight nit set of well known friends. You don't need to pay attention.. To such things.. But if you add people your not 110% sure are alright.. I would listen to your boyfriend cause he is only looking out for you. Hope it helps :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
