Am I wrong in interpreting that as how it works? Seems like there should be a pretty big distinction there. Often, its faster to use the "upload to danbooru" bookmark script than go and reverse image search it, while trying to see if its a variation or lower quality that has already been uploaded.
E: i think i am reading it wrong, but im confused as to why it says i have 30 deleted posts on my profile. Clicking on that only shows 28 [status:deleted], but clicking "count" says theres 33? why are there 3 different numbers??
