I have just woke up, and in one of the forums there are 3 pages full of spam, so, my suggestion is either add a captcha when you are posting to prevent bots, or add some kind of antispam (eg. if you have just created a post, you won't be able to make a new thread in the next 2-5 minutes), or if the web detects you are posting to much similar content, disable you creating new threads until a mod checks your posts (the post you have created last would become private), or add all of them.
