I don't have any accessibility disasters to share, but I'm going to make an offer (and, it being a free offer, all caveats about getting what you pay for apply here). If you have an internet accessibility problem that can be fixed by throwing text at the problem (e.g., images lacking descriptions, important information given only through spoken words without any kind of captions, unwatchable flickering videos), I'm offering to throw text at it for you (i.e., I'll transcribe things or whatever).
