A backup of FtM artist ScreamFTM, sourced from direct site downloads back around ~2019, when their pages were still live.
https://www.furaffinity.net/gallery/0905kj/ (Still scrapable via TOR backup) https://www.deviantart.com/screamftm (Manually scraped 12/10/2019, Nuked before Gallery-DL run)
--https://twitter.com/scream_ftm may or may not be owned by the original artist, but it's out there too. ---Same with https://www.pixiv.net/en/users/25336455
As I recall, there may have been a handful other pics I did NOT grab at the time - mostly comprising particularly masc or bearded FtMs - so this may not be a 100% full backup. If anyone has them lying around, though, just throw them my way via DM and I'll add them to the set.
Note that I've also scraped literally thousands of other art accounts, for every eyecatching Transformation and Transformation-Adjacent (IE Hypno, Trait Change...) specialist I can find - so if someone you liked got nuked at any point post-2022, check the 'interests' section of my profile for an availability list, give me a DM if you see something what's been lost, and I'll see about throwing them in a gallery too.
