Images shared between tweets? Different tweet id, same image source urls?

This account (VERY VERY NSFW WARNING) seems to be creating tweets with media it's previously posted as new tweets and definitely not retweets, but the content appears to be blue instead of red, indicating they've been downloaded before? Is twitter doing some checksum recognizing here, because these two different tweets here and here use the exact same file urls? tcas correctly identifies I've downloaded the image before, but of course the filename will be different if I try to save it.

I can't say I've seen this on any other account across twitter.

Yes.

It's strange. I tried to post the same images multiple times in different twits, Twitter always uses new URLs for them.

I'm not sure that it makes sense to change the archive format ID only for this case. It would be the same thing as archive history wipe. (Although, technically it would possible to manually recalculate them based on the downloaded filenames with a script, of course.)

So perhaps it's a non-issue for now, but something to consider if Twitter starts doing this going forward.

Triage, if you will.
