I am asking this because the site itself looks dodgy, has other ads on it which makes it feel like a spam website. 

Heyy, i literally had the same thoughts when i started with them. I use Aw all the time and decided to give them a go. I buy some of the additional features and get a good client flow, so when I need more work I create an ad and post it. Site is trash but the featured makes me standout
