did you know that if you save an image off of 4chan, the filesize gets compressed slightly?
most of the time, it doesn't really change anything, but when people are posting the same images with the same text over and over again, it becomes a way to indicate who's posting with multiple devices
so let's take a look at this one

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+a+thick+curvy+Fraiki+in+this+pose.&offset=24

ref goes from 1.88 MB to 1.40 MB

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+Coyote+having+her+surprisingly+big+tits+&offset=72

2.23 MB to 1.66 MB

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+Gummi+%28her+new+design%29+in+a+situation+similar+to+the+reference

flip-flops between 1.05 MB and 809 KB
weird coincidence, huh?

let's take a look at a couple others

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+this+pose+with+Kobo

let's look at the timestamps this time
this person seems to have posted this one on every waking hour at least once
that shouldn't happen with a person that has something called a "sleep schedule", should it?

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+this+meme+with+Ecto+the+eldritch+rat+&offset=24

this one too

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+this+with+Irys%2C+except+that+instead+of+a+credit+card%2C

and this

now we look at these two...

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+Botan%2C+as+shown+in+the+reference+on+the+right.+It+does+not+need+to+be+exactly+the+same+expression%2C+but+I+am+basically+thinking

2.34 MB and 1.75 MB

https://warosu.org/vt/?task=search&ghost=false&search_text=Requesting+Fubuki+vibing

432 KB and 369 KB
