Spam takes many forms. All of them waste time.

Fake signups

Bogus registrations clog your user list.

First-post spam

Spam posts appear minutes after signup.

Profile spam

Links and promos hidden in profiles.

CAPTCHA complaints

Good users hate extra steps and abandon.

Moderator overload

Queues pile up and important items slip.

Lost sign-ups

Real users give up before joining.
