john.doe said: Why was this Pixiv version deleted? It's bigger file size than the Twitter version. Shouldn't the Twitter version be deleted instead?
Just undeleted it to have a look at it, and it turns out that It's the twitter version that has a bigger file size this time (497KB vs. pixiv's 496KB).
Back to deleted for now (was deleted by the uploader themselves).
I've re-downloaded both version and compared them again, the Pixiv version is 515.95 KiB, while the Twitter version is 505.84 KiB. I've also tried to upload the Pixiv version here but failed due to the reason "This post already exists: post #613667".

It's said that yande.re removes some of the stuff from the uploads (e.g. some of the EXIF). Not sure if this is related to the size differences.
Twitter now no longer re-compresses JPEG images up to 4096*4096px and 5MB [1].
So it's possible both Twitter version and Pixiv version have exactly same quality pixel-wise, which is the case here
C:\sync\code\python\image_compare>image_compare.py "yande.re 613595 r_o_ha sweater.jpg" "yande.re 613667 image.jpg" Sizes are identical! (1500x2566) Color modes are identical! (RGB) They are pixel-wise identical.
