Is Instant Blog Subscribers legit?

The site looks good, talks a good game and seems to be generating a lot of interest! It just feels a bit odd that the only way to contact them is through a message ticket. There is no fee to join but there isn't much point in doing work for nothing if they don't intend to pay anyone. If somebody can give me their take on this, I'd appreciate it, that way I can decide if it's worth my time. Thanks!
