The testimonials by "@james", "@yoni", "@ktyr" are pretty obviously not real just from their implausibly short Twitter handles. The actual Twitter handles have different profile pics that simply don't match the ones displayed on the landing page. For example @ktyr is not an Indian male but an Asian girl who hasn't tweeted since 2012.
@prem_saini1 also is not the same person.
@emarky is the same person, but he doesn't seem to have tweeted the testimonial.
As I said, I'm just really bored :)
