Most of the time when I like something the heart animates in, and then (ostensibly when the network fetch round-trips) it animates back out and the count goes back to where it started. My tweets also average a solid 7-13 views, so when I was getting 429s back after not posting within 24 hours, I figured the shadow ban was just getting more transparent.

Whether it is or isn't, twitter definitely feels like it's dying from my perspective. My account was created sometime in 2008-2009.
