Can you use WordSwag commercially

Can anyone tell me if I can use Wordswag commercially?

I had never heard of Word Swag, but a quick Google search turned up a response supposedly from their support people that said,

WordSwag uses fonts and images from a variety of sources which all have different terms. Commercial/marketing purposes should be okay, but as far as selling a design for profit (as a poster, image, t-shirt, etc.) that might not be okay depending on the exact fonts and images used.

So the safest route would be to stay away from actually selling the designs.

Here’s the link to what I found.
