i got warning from my VPS

[mehranexpert]

We've detected an outgoing Denial of Service attack (http://do.co/21Y1Gc1) originating from your Droplet. Specifically, we have detected inbound traffic exceeding 0.01 Mb/s and outbound traffic exceeding 781.34 Mb/s. Due to the traffic’s harmful nature, your Droplet was taken offline; this means it is not connected to the internet and all hosted sites and services are unreachable. We know that this action is disruptive, but it’s necessary to protect you, our network, and the target of your Droplet’s attack.

am i shouldn't run it on vps ?

Quoting the README:

The software will rely on your main DNS resolver in order to enumerate subdomains

and

someone might not like such behaviour

... they just don't like the outbound DNS traffic you're generating :)

You could try to reduce the number of concurrent consumers ( -consumers option ), let's say to 1 or 2, but if the Droplet has enough hardware resources and bandwidth, I don't know if it's gonna change anything.
