Hello Guys! i'm tired of trying to deleting all messages from facebook. but there is no way to deleting all messages. have you any trick for this??
Actually, even then it's not possible. Facebook never deletes anything, it just marks it as hidden. You can request a copy of the information they have on file for your account, and included in that information will be everything you ever posted and deleted.
this is not allowed in facebook because facebook thinks that conversations or PM's are importance and they don't wanna give anyone option to delete these in one click or accidental. by doing this you are secure. but if you really want to delete, you have to do one by one.
Maybe you should think about the suitability of your posts before you post them? If your posts could be construed as spam then your strategy isn't right.
