@soaproot When I see a new person not using alt text, and I get the feeling they might be receptive to a suggestion, I send a DM suggesting (not demanding) alt text, with quotes from two people explaining how much it means to them. This has been pretty well received. Sometimes they just don't know!For old timers, I just block. (This assumes it's not someone using the alt4me hashtag or otherwise indicating a disability which might impede using alt text.)
