Well, it was an eye-opener.
Every ten minutes, the IP address 18.104.22.168 hits my RSS feed.
Every. Ten. Minutes.
22.214.171.124 is squaretrade, but the block maps to:

Eh. I have no idea who that IP address is from, but I assure you, I don't write enough on this site to ping the site every 10 minutes.
If that is your IP address and you're here to figure out why the feed stopped, I blocked your IP address. Pull it back to once an hour, and not between 3:10 and 7:00am (because clearly I don't post at that time of the day), and I'll unblock your IP.
I turned the stats back off. I still care little about them.
