Deviantart and Blogspot are easy to immidiately disregard as those are far more compressed and other is censored.

This post, furaffinity and tumblr are all 1:1 visual match, so the user somehow managed to save the JPG as PNG file before uploading it. This version is thus considered to be inferior to furaffinity and tumblr sources. If there was any indication that they did this knowingly it would warrant a warning, but I don't see similar from this user earlier and there's no direct post relations or MD5 matches to other versions, meaning they didn't save it as PNG to replace other posts or circumvent dube detection.

Also not sure how they managed to get visually identical version from tumblr apparently, when they sourced _1280 version which is slightly more compressed from _raw.
