Options to avoid spam

[Grant]

Hi Brad,

Here are some immediate things we can do to stop spam. These are agnostic ideas, I know some are not warming to a new community;

1 - Admin approval for newly registered users

2 - Links aren't allowed to be posted until ~10 posts minimum

3 - Confirm e-mail address upon registration -- Just enabled this

Like #3. Thanks for implementing this. Regarding #2 I read that 3 posts prior to links is effective. 10 might be too much?
