The PublishingPaidMe tag on Twitter is to expose the difference in advances between white and POC, especially Black, writers. There's a lot of data to process, since there are big differences in how much large Big 5 publishers pay compared to small independent publishers and also YA vs adult SF/F vs MG vs mystery/crime etc, and the advances don't take into account royalties, audio and foreign rights, etc.
N.K Jemisin explains a bit about it here:

https://twitter.com/marthawells1/status/1269387266100801538You can see, my advances are not large. I make most of my income from royalties after 2010, and audio and foreign language rights. For my earlier books, Wheel of the Infinite and the Ile-Rien trilogy all tanked and never produced royalties. The Death of the Necromancer did well, but was jointly accounted with Wheel of the Infinite, so it never produced royalties either.

I put my hand up and said that publishers didn't take me on either, so I published my books independently, and I recommended everyone should put their own work out that way without censorship.
