Most of those got absorbed by reddit for me. Reddit has some awesome characteristics. But over the past two years it's becoming more and more bots. You used to be able to make a reddit account without an email, now you can't for obvious reasons.
You can still make an account without an email because reddit doesn’t verify emails. You can put whatever you want in the email line. I have made dozens of accounts this way. No idea if the associated emails are even valid.
