Could ignore be implemented without logging on or even adding a check box to not accept messages from non friends. Its a bit of a pain when people message you and you cant block them without logging in.

I don't have email notifications for FP but i get that some people do....is that what your basically saying in your post? You get a notification so you log in to check, to find its some randomer? If thats the case, best turning emails off.

Would it be worth blocking them anyway? Cos if like me you get messages you dont want/need or can be bothered with, they only deactivate and make a new name up to send you more anyway!

Dunno if ive made any sense to you there but i have in me own head
