I’ve been going through my posts and a lot have been replaced with larger versions. I don’t really care other than the fact that it says I’ve been penalized on every replacement. I only upload from mobile, and I’m new, so I don’t really know how to make images larger yet. I just don’t want to get in trouble and banned from posting.

You should learn, otherwise this is exactly what will eventually happen. Start here: howto:sites_and_sources

In your case, some more specific advice would be:

• Do not upload from Rule34 (either of them), ever. If it is larger than the image available from any real sources, that means it was pirated from paysites and will get deleted anyway.
• Do not trust any version of a picture you got from DeviantArt that was obtained by means other than the download button.
• I don't even know how you managed to mess up the Twitter posts. Did you take a screenshot or something? In a couple of cases, your files somehow managed to be larger in terms of filesize while smaller in terms of resolution, so that can't even be explained by uploading a thumbnail. In general, when uploading from Twitter you should always use the URL upload method, and the URL you put in there must end with the string "orig", as all of your replaced posts now include in their sources.

Not sure how much has changed but this could be the problem. Some phone browsers will mess with images you save, so you either need to double-check that's not happening or use the URL upload method mentioned in the post above.

Ugh, every time I an anomaly like that, I zoom in close to see if it's just an upscale, or there's (better) a better source than either of them. I have seen PNGs with lower resolution but actually more detail. The slightly-larger JPEGs were either blurry screenshots or upscales with horrible artifacts. Either way, in these cases, the PNG was often a (much) older source and very damn likely original. :facepalm: I've also seen people resave a JPEG as PNG and "weird, that PNG has compression artifacts, hmmmmmmmm" happen.

assuming you're on mobile given the discussion here, but this is also a problem with the GNOME image viewer, but opening Gimp keeps all the pixels crisp. you can use another app to see the image in detail.

I do know of a couple of artists whose most reliable source is Rule34 (and it's definitely them, they link to the posts on their other socials). There are exceptions to everything, you have to learn when and where to push things

I meant I find files that likely came from a mobile user. I know that trap very well. Yeah, I even did a replacement where they were clipped between multiple comic pages because it was a careless screen shot. The pain of figuring which to replace and which to just upload and add to pool... Screenshots are awful.

I wonder if any of the popular mobile screenshot apps create metadata we could extract and automatically forbid in the uploader? The chances of a legitimate artist using it seem slim, and most external sources strip all metadata anyway.

https://old.reddit.com/r/Android/comments/7b1cb2/til_android_screenshots_dont_include_any_metadata/ Hmm, looking at that makes me think the original filename has an easily-searchable keyword on some of them because of default names. The files I replaced came from a site and not from the uploader's own phone, so probably had it stripped, sigh...

https://dev.exiv2.org/projects/exiv2/wiki/The_Metadata_in_PNG_files Although a PNG screenshot is probably rare.

There are rare cases where images are cut/broken up badly at the source, like this pool https://e621.net/pools/27169 (a lot of the pages with the husky dog), though I'm unclear if the posted sources are the original source or are screenshots from a now-dead source. So you can't always blame the uploader, but most of the time it is due to not following the instructions.
