There are many services in the crypto currency community and there have been many scams, hacking and thefts. New users have fallen victim to all manner of fraud.
There would be much benefit from having multiple, competing ratings organizations for the many crypto currency services. These organizations could rate all the services from exchanges, online wallets, markets, software developers, newsletters, hardware manufacturers and the coins themselves.
Crypto-currencies are not regulated by any government. One of the points of Bitcoin and other currencies to be free of government regulation, but the free market can regulate itself. Even in the anarchist dream of having no government, there would still be schools, police and fire departments, but they are privately operated. Let there be privately operated ratings organizations; more than one so any bias from one group can be counterbalanced by the others.
Such a board could do its research and provide professionally written and well documented reports (with many footnotes, links and references) using their own standards for what constitutes a good or bad coin. It will still be up to the user to determine if the board knows what they are talking about. If a user could read three well reports from three different rating boards, he/she could hopefully make up his/her mind and have an informed decision not to invest in an IPO of a user with an activity of 3.
These boards would have their hands full scouring the internet for all the information for their reports.
