This extension is polling us WAY to aggressively.
I am noticing about 1.5 hours of processing time from your account in the last 24 hours (@alep), hitting /latest OVER and OVER again.
My estimate is that this is hitting /latest every 10 seconds, its not even sending a user agent so we can not easily ban this.
Recommend you pull this extension and reimplement using the message bus, it can notify you when new stuff is available.
