Artists I follow post mostly either on X or Instagram, which I don’t find to be much better of an alternative. All that have mastodon or bluesky accounts I’ve switched over, but many do not because there aren’t enough users.
But I haven’t actually tweeted anything for something over a decade now?

Which would still not be perfect because “foo@bar”, “foo@[123.123.123.123]” and “💩 @[IPv6 :::1]” are all technically valid email addresses.
It looks like the only validation that doesn’t block something valid pretty much would start and end at “It has at least one @ symbol, and something on both sides”.
