Why is she ticked off at you now? I wasn't sure why she cut you off the first time--was it based on an incident where you guys into an argument of some kind, or a perceived insult? Or did it seemingly come out of nowhere? Cause, if the latter, that's an incredibly stressful thing to do have to deal with--effectively always trying to guess if the next thing you do will cause another rift. I am sorry you are having to deal with this, in any case. I myself might not understand the 'no pics on internet' policy but I would absolutely respect it, and be really embarrassed if I forgot someone's policy.
His mother blocking him on facebook but posting pictures of his kid seems really odd, too!
