Ahhhhh.....
I had this a while ago, totally stopped receiving them and thought it was fishy...
But my ISP sends me a list of all the "Spam" that they've filtered out of my account on a regular basis. Out of curiosity I opened on of these "Spam" lists and Lo and Behold, all my P8nt-talk notifications were in there. I just set that as a trusted sender and lo and behold, they're back again.
So i'd say check your FSP spam filter
