However, the best way of doing that seems to me to be (a) to document somewhere that site <whatever> is a known malicious and unreliable source and things there should not be trusted, and (b) to close such discussions down politely and inform people why we don't want such issues brought up again.
I think this would be a great approach. If we have a superpower, it's documenting things.
The remedy also fits in well with how we handle a lot of conversations that are both perennial and annoying. Instead of deleting the comment, somebody just says, "That's already been discussed thoroughly at WP:XYZ. Consensus seems pretty established, but bring it up there if you want to change things."
