vbulletin autoposter

I have a 10+ year old Vbulletin site that has about 5,000 unique visitors a month. I've been using Google Adsense which I make about 30-60.00/month on. Recently I added Amazon associate banners. Does anyone have any suggestions where I can increase my revenue?

I'll be biting the bullet and investing some money to build an authority site with a forum and want a bot to help me populate the forum to make it look like I have a community happening. Is there a bot that can scrape other forums and make posts on mine to help me do this?

Looking for a software that can post a new thread to all my niche specific Vbulletin/phpBB forums? also be able to post on a certain topic. Any ideas? :(
