i read about this elsewhere on bitcointalk and i have to say, they seem to be trying to manipulate the market in their own way. specially with all the noise they are making for their useless and baseless rating of cryptocurrencies!
by the way someone found something very interesting about their history of manipulating the market for which they were prosecuted:
You may also want to consider the fact that Weiss has already been prosecuted for "production and and distribution of materially false and misleading marketing materials" (false ratings for pump and dump basically lol) before:
