I recommend changing the UA to something other than "Ruby". Maybe "Watergun-v1" for example. I noticed a couple of probes within a 7mn interval. So is the 15mns worst case?
Thank you for pointing that out, I changed the UA as suggested.
Probably the first request you had was the "validation request" in the sign up process, then we check every 15 minutes using a (very naive) cron job.

Good luck!
