I shared a link to an answer on reddit which also contains my SO id. In 3 days it increased with more than 1400 views which probably could have 1000 unique IPs and surely passed the 25 and 300 unique IPs thresholds, but none of the Announcer, Booster, Publicist badges where given.
According to this Q&A: Timeframe for Announcer, Booster, Publicist badges and this: Do shared link to ANSWERS also count for Announcer, Booster, Publicist badges? the above mentioned badges are given also for answers.
Are Announcer, Booster, Publicist badges given later for answers through a weekly(?) script or the unique IP mechanism failed somehow for this particular link although it contains the id?
