I checked the /r/blind sub and they have started their own Lemmy instance. Edited so Blind users can read it.

Announcement!!Open Alpha!! RBlind - A community on Lemmy, brought to you by the moderators of the /r/blind subreddit.

Since the news broke regarding the forthcoming changes to reddit’s API and the impact that will have on the third party apps and tools many of us rely upon the mods here at r/blind have been working on an accessible option for those who either cannot or will not be staying on reddit. As talk of alternatives like mastodon, lemmy, and the like have increased we decided that it would be best to reveal what we have been working on, hence this post. Several days ago we shared this with those of you on our Discord server and have been asking for feedback.

This project is by no means finished or polished, and is currently operating on development backend code and a beta UI to allow for access to still unreleased features that our community needs such as up/down votes displaying state changes, and nested comments, read this as there are and will be bugs and outstanding accestsibility problems. However, the advantage of this platform is we control the servers, the UI, and can fix accessibility concerns ourselves instead of relying on a for profit company or the generosity of app developers to do it for us, not that the latter is unappreciated.

So please be understanding of the above and we hope those of you who decide to join and see what we have done so far for all of us, and please report problems as you find them.
