Reddit is terrible as a website. But it still has the communities that developed there over years, and they are an invaluable resource. They are definitely positioning themselves to pull a Digg, but until the Reddit-killer comes along with a mass exodus (and it doesn't look like it's gonna be Lemmy unfortunately) access to those communities will entail dealing with reddit.
lot of subreddit doesn't move yet.
Move a communities is not easy.
If the community is your business (game, company specific, or fandom, movie, ...) moving is lot more difficult.
It is possible to use Reddit without having to log in and deal with the shit mods and community. Apps like RedReader (similar to old school RiF) allow you to bookmark subreddits locally if you need to access the site as a source or whatever. I haven't logged in to participate for months and I havent missed it at all.
If you must use Reddit still, then it’s pretty easy to sign up for an email alias service. Or just make a trash email and send everything for social media to that. There’s also plus addressing, although that doesn’t protect your privacy, simply makes it easier to filter out spam and see who is selling your email.
Idk, I use Proton and mine worked fine. It’s super easy for services to keep adding new domains, so it would be a lot of work for Reddit to keep up. Not to mention money, since most services don’t list all their domains to the public, you have to pay to see them.
