In the last couple of hours I have received 4 Announcer badges. Two of them on Super User, one on IT Security and another one on ServerFault.
This seems slightly abnormal to me because probability of 4 announcer badges suddenly being awarded within short period of time is rather small on my understanding.
I just double checked and found that all these badges are duplicates. I had been already awarded Announcer badges for those questions in the past.
Can somebody look into this?
