Pixelfed Uptick in Monthly Active Users

https://pixelfed.fediverse.observer/dailystats

I don't even use Pixelfed, but its growth is kind of interesting to me:

• its recent rise
  
• its subsequent plateau
  
• its (expected) ebbing
  

The ebb lasted a lot longer than I was rooting for. But now it seems to have caught a recent uptick. Still slight in terms of its maximum peak, but respectable: 47K Monthly Active Users. (about the same as the total number of MAUs on Lemmy!)

Furthermore, it's also reflected in the half-year Active Users, meaning it's not just people who signed in a couple months ago who are now checking back in -- looks like brand-new active participants.

Any idea what caused this? Another "migrate" campaign? Did Instagram do something stupid again? Or is it just a data glitch?
