I've been getting these blank notifications, from idk who but it had no name to it or what the notification is about, it's just a anonymous profile picture and that it. What exactly is this about?Here is what I mean:Edit1: @Ballom, I guess that is a possibility, but then I wonder why so many all of a sudden. This hasn't happened before, it started happening I think around the end of May.Edit2: @ToaBalta thanks, this clears things up a bit, its like some digest about topics so i guess thats why. thanks everyone.
