This morning two strange posts appeared in your RSS reader about your feed being reset and your subscription being expired. This was a mistake on my end, but ultimately a useful one. Let me explain.
However, as you have obviously discovered, I haven’t turned the old feeds off yet. I did, though, temporarily forget that they existed while creating hidden posts that are inserted into feeds when — as you guessed! — they have their tokens reset or subscription expires.
In this case, though, those posts didn’t apply to you, and I apologize for the confusion.
(But remember this specific feed will be turned off in the near future!).
