I generally scroll a series/character tag before uploading to make sure it's not there but do sometimes miss stuff because of difficulty I have focusing so kinda rely on the MD5 to occasionally correct me when I overlook something.
I get that there are different MD5 sums which happen when people edit an image, or stuff like when Pixiv automatically downsizes it to a lower resolution...
But I get confused about why when the image isn't changed and the resolution and file size appear to be the same why the MD5 didn't detect it and reject the upload.
If it did that then we wouldn't have to worry about having a "deleted file" count against us forever :(
For example:
Nov 25 https://e621.net/posts/2503246
Nov 27 https://e621.net/posts/2504961
I'm not sure what the mental hiccough is where I didn't notice it was there, but the same res and file size is displayed for both:
2427x3000 (2.12 MB)
Anyone have an idea what might've differed between the file I saved from the 8chan.moe /delicious/ thread where it was delivered to my request?
as opposed to the upload saved from Baraag.net ?
Something about one site or the other might somehow be tweaking the files submitted to them (I assume the artist attempted to upload the same file to both sites) which results in MD5 changes?
