Flood of keyword alerts to iOS since last night

[Raj Gandhi]

What is going on?  My iPhone says 911 keyword alert notifications in the last ~10 hours.  Am I getting everyone's keyword alerts?  I'm not getting the same alerts on the biggerpockets.com website.  Therefore, it looks like it is only alerts to iOS.  The problem isn't because my keywords are too short or are a wildcard.  The notifications are for keywords I didn't subscribe to (2%, rental, etc...).
