Ask How do you prevent spam accounts on a membership site?

[SuperAffiliateX]

Spam accounts keep flooding my membership site and I don't know how to stop them. I want only real users but fake sign-ups keep coming in. Can I use captchas, email verification, or something else? I worry that adding too many steps will turn away real members. Is there a way to block bots without making it hard for people to join? I also want to prevent spam posts without spending hours deleting them. What's the best way to stop spam accounts on a membership site?
