I provided CDN services to - providing a network of low latency caches for them to deliver via

Their site was essentially a date sorted index of various subreddits - somewhat unsurprisingly, with a focus on various NSFW subs. As a result, they occasionally received DCMA takedown requests, but because of the setup on their origin were quite slow to process these.

This periodically resulted in me, as a provider, receiving an escalation from the person complaining. So, to remove these disturbances I created a small piece of software so that the site operators could process a takedown by inputting the URL path - that path (and all associated images) then get blacklisted across my edge, preventing any further delivery, while they continued with their process on the origin to remove the content at source.
