Massive automated spam
The problem is simple - it's not an account registration matter. I don't want to force people to register for an account, go to email, confirm, go back and login and take out an ad. It's simple but there is a problem with robots knowing appthemes' theme and autosubmitting ads and bypassing the ad submission process.
What this theme desperately needs is a required captcha of some sort on the one of the final pages, at the very minimum. While none of the ads are approved, I get hundreds of pending messages from ad submissions awaiting approval. Something needs to be done to make autosubmission bypassing the several entry screens impossible. This is, at least from my experience, a problem with this theme from appthemes and it needs to be fixed asap. No anti-spam solution will solve the ad submission process that requires its own solution.
