One way that Valve could address this would be to blacklist servers
that are seen using this tactic, or to penalize them in the list. It
wouldn't be terribly difficult for them to test for the technique in
an automated way, but they could also do it by hand in response to
reports. They have used these techniques for handling other types of
abuse.
And how has that worked out for them? Let's see
1. Implemented the requirement for servers to have a token which linked
to the owner's steam account.
2. They banned weapon skin addons.
And now the servers just shuffle tokens while running the skin addons.
Seems like Valve lost that one.
I think the concern here is about someone proxying queries at the
edges of a multi-PoP network and giving out fake responses.
As far as I can tell they have leased IP space from Prager, had it
announced at vultr/choopa and are leveraging vultr's anycast.
(92.119.148.0/24 <https://bgp.he.net/net/92.119.148.0/24#_dns>)
let's not go along with the misuse of the term "anycasting"
Let's not say someone is misusing terms when you stated yourself you
didn't look into what GFL were doing.
Spoofed queries (the DDoS attack that this theoretically helps with)
are relatively uncommon and such attacks are rarely large, so this
behavior would not be necessary from a DDoS mitigation or routing
standpoint.
Utilizing anycast you can have your endpoint completely unprotected, but
have traffic routed through a protected network. It doesn't have to be
just for filtering query attacks, they're already leveraging the vultr
anycast, why wouldn't they use vultr/choopa's mitigation as well?
Furthermore, if you actually feel that GFL are acting maliciously you
could always kick them off your network. If nothing else, it would prove
a point.
