I've seen that some subreddits went dark and said they'd come back in 2 days (June 14th), and others said they'd go dark indefinitely, until the API changes are rolled back. I'd like to make an appeal for the admins who're willing to go back: please don't.
I think Reddit wouldn't withstand 2 weeks to a month without their largest subreddits, and maybe they'd change their minds about API changes. Some may say they'd just make the subreddits public again and promote someone to mod (which I totally agree, they'll probably do that if the blackout endures for too much time), but I think most people don't realise the PITA it is to be a good mod, and just want to be one because of the status (I'm not an ex-mod btw, I just heard it is very complicated to moderate and I believe it really is).
Secondly, there's no guarantee that Reddit won't pull the rug again. Even if they roll back the changes and everyone goes back, they'll probably come up with this strategy again some time in the future. So instead of going back, stay in the Fediverse: all applications are open source AFAIK; you can run your own instance if you wish; you can defederate other instances if you wish; you can contribute with new features you miss or create a fork aplication of your own if you want to; heck, you could create your own Fediverse application if you want. And there won't be a scumbag to come and try stop you.
On Android there's an app called Redact that will scrub your social media accounts. I used it on my reddit account and it worked well.
Thanks for letting me know of this. It is even cross-platform... Works pretty much on everything. For the ones who are interested, here's a link: https://redact.dev
