Netsweep likely provides a BGP feed for its filtering. It is up to
the network service provider to decide whether to route the traffic
based on that information. The general practice is to configure
filters to prevent network-related problems. It is unusual to
override the routing policy advertised by the network service
provider. 104.27.192.0/20, for example, originates from AS13335
according to Cloudflare. That information can be validated as there
is a Route Origin Authorisation (ROA) for the prefix.
