I'm a Disabled person that wishes more people would use the #Alt4Me hashtag. If you can't write/dictate/put a media description, I'd love it if someone else did it. That hashtag is not just for Blind or low vision people. It's there if you can't provide an media description yourself! There are groups that do the same thing. Anyone should be able to use the tag to request a description without getting harassed for it. If you do provide audio transcripts for an uploaded audio or an image description, tag with #Alt4You so others can find it!
There's more info in the accessibility category on Fedi.Tips, https://fedi.tips/ Also, today I learned about @closedcaptionsbot
