I thought cryptostocks is like an escrow that holds onto their bitcoins until the actual product or services is released.
But the minimum requirements for crypto-exchange is so low:

    Your project must have a website with an own domain
    The registration of a new project must be made with an email address from that domain.
    The listing on Cryptostocks must be mentioned on the Website.
    eMail us the contract text so that we can review it.

Reasons for delisting
The Exchange may choose to delist a project for reasons such as (but not limited to):

    violation of terms and conditions
    very low trading volume, with very low trading volume defined as less than an equivalent of 10 USD in a period of 100 days.
    fraud, scams, illegal activities
    discretion of the Exchange


This is not a scam proof exchange. Unlike real stocks, it has not been reviewed by the SEC. They could be mtgox at the launch and say the transaction malleability lost them 1000000000 coins after 1 day.
