AdultAdWorld vs. AdEngage?
 

What is the difference between http://textads.adultadworld.com/ and http://www.adengage.com/ ? Is this the same company with two sites?

Difference is aaw support zango and trojan installers sites,meanwhile adengage not.

In AAW for Buy Ads there are 2279 results, while in AdEngage for Buy Ads (content rating - Adult) there are 2256 site results. So AAW has only 23 sites that have zango and trojan installers?

And also why would someone buy advertisement from both sites?

AdEngage = mainstream version
AAW = adult version
