I have two twitter accounts. One is the one I generally tweet from. The other I have tied to automated things. When my computers upgrade or reboot, they tweet to that one. Each account follows the other.
One of the things I do is use it as an interface to track my coffee intake. When I drink a cup of coffee, I (acc1) dm myself (acc2) a message of “d acc2 drank 1 coffee”. I have done this for several months.
This morning, the message I have DM’d myself several hundred times stopped working, saying “You cannot send messages to users who are not following you”. I’m DMing myself from myself. I have been DMing myself nearly daily for almost nine months. What changed this morning? And, how can I adapt to this change?
