Yes, you can send a DELETE to a Discord Webhook, but these malware projects have clocked on in most situations and now forward Webhooks through their own domains.

For the example of PirateStealer, the kid who made it ran a website where you posted your webhook and it spat out an exe that hid your webhook behind the domain, they even sold "premium" copies with additional security but in reality once they put the webhook behind their own domains they were dual-hooking, so the information was actually sent to 2 webhooks instead of just the 1.

Most of the services to create this malware now hide it behind a domain rather than directly exposing the Webhook, so shutting it down isn't as easy.
