Is there any way on Mastodon to automatically filter out image posts with no alt text?

Edit: think I've got my answer- thanks y'all!
Edit 2: Copy-pasting my reply to compile the solutions from the comments: The best solution for my usecase (mobile on iOS) is Martin Wenisch's fork of Phanpy (https://mastodon.cesko.digital/@mwenisch/116249807965211752)  but if you're on Android the Moshidon app client is also an option and if you're on PC there's uBlock and Tampermokey scripts (https://neilzone.co.uk/2024/02/suppressing-posts-containing-images-with-no-alt-text-in-the-mastodon-advanced-web-ui-via-ublock-origin/ & https://social.jpoesen.com/@jpoesen/116250073497451531)

@[email protected] I did a quick fork of Phanpy (web client) that hides posts with images without alt text. It's on the client side: https://github.com/cheeaun/phanpy/compare/main...martinwenisch:phanpy:main I wonder if this would be an option. It'll be hard to push it to the upstream, as it's out of their scope. But if enough people would use it, I'd polish it with a settings switch and try. Deployment of the changes here: https://phanpy.muhu.digital

@cryptids on the web app you can use ublock filters to do this

@lily I'm an old lady with a computer and don't understand all of the lingo or the applications mentioned. However, if there is a solution to be had, who would I write to on Mastodon, myself, as the above-described non-techie?

@Lizette603_23 from a quick glance at the mastodon website, the following filter should work:##.status:has(.media-gallery__item-thumbnail img:not([alt]))


this will hide all posts that have an image attachment without alt text
note that if mastodon devs change the layout of the page, this might stop working

this filter is written for uBlock Origin, which is an ad blocker
to add the filter, click on the addon's icon, then open the dashboard (three cogs icon), then go to the "My filters" tab, paste it in, and click save
