I got one with crypto addresses for "donations" for the first time today. That seems to be a new addition, messages from 2, 3, and 5 weeks ago didn't have them.
I have also received some "alternate" versions from pseudo-random usernames (ones not on your chart) from the sh.itjust.works instance. Mostly the same copy as always, but delivered entirely in an image rather than image+text. Thought that was interesting.
