There are tons of posts about how there are lots of scammers and fake profiles on this site. Since this site (and others like it) requires only an email address to sign up, it's no wonder there are lots of fake profiles since it's super easy to create multiple email accounts. So what are your ideas on how to make it more difficult for a scammer to create an account?
For example, sms verification. Scammers can still create a fake phone number, but it might at least reduce the number of fake profiles. A site's admin should also be more proactive in removing fake profiles, but what more can be done from a programming/registration standpoint?
