[Hammer]

Here's what you do to beat the spambot.

Step 1. No one is allowed to post a link or an image until they've made 10 posts.

Step 2. Ditto until they've replied to at least 10 posts

Step 3. Ditto until they've replied to a second email (sent after the first confirmation email) that contains a question that only a human can answer. Once they reach 10 posts and 10 replies they get an email congratulating them on becoming a full fledged member of the club and informing them that they are now able to post links and images, after they reply to the email and answer the question. The question doesn't need to be difficult, maybe something like what color is Oprano's background? But, only a human that reads the email will be able to answer the question.

Step 3 (option). Instead of an email, set up the script to automatically send them a PM letting them know they will be able to post links and images as soon as they reply to the PM.
