RiskIQ is kind of "private Google" which crawls and index entire Internet. Unlike Google:
On my websites, the estimated number of their "visits" is comparable to that of GoogleBot (tens of thousands per day).
I would like to block their bots as I do not like to pay for CPU and bandwidth serving those bots.
Google at least brings some traffic to the website, but serving RiskIQ bot is a pure waste.
May "Cease & Desist" letter help here ?
