The Time Tracker saga continues

Every­one got anoth­er mes­sage today with my race results. Here’s my lat­est missive:

Thanks again for this expla­na­tion, but I still don’t see why I and every­one else on my list are con­tin­u­ing to receive mes­sages from your com­pa­ny 72 hours after the race fin­ished. Sure­ly this is not what you intend­ed your sys­tem to do. It’s def­i­nite­ly not what was advertised.

This is absurd. Is there any way to stop these mes­sages from spam­ming my friends? This was sup­posed to be a REAL TIME ser­vice. What part of “real time” does your com­pa­ny not understand?
