Using there site for free why not. But it gives little next to no advertising support since the site has almost no traffic. Look at how small their Twitter account and Facebook following is.
However, they still charge for premium services all of which I have used are a scam. You won't get 60,000 impressions when you purchase to be featured for $150 like they say. They provide no metrics or analytics to provide proof, the media pitch at $99 which they say is at the value of $1169 by going somewhere else is not true, and media list they sell is garbage with bounce backs where you are better just going on Fiverr
