Not what they claim to be
While this company claims to spread your name, they blanket spam any un-moderated website they can find, without caring if it's a site that represents potential customers for your service. As an example, they spam the Writers Cafe website with phony reports, and advertisements, presented as "stories." So not only are they not bringing you customers, they are making people like me angry enough at their lack of ethics to honestly review the character of the company they are spamming for.
They make sweeping claims, but in reality, less than trustworthy.
And, after having been asked not to spam our site with their pretend stories, they were at it again today, 3/12/19, and yesterday, too, making it 114 spams forced on the site. I'm sure they tell their customers they're working to improve their business, but I'd certainly not buy from someone who hired them. Would you?
