Yeah, if you don't find any competition, that's usually not a great thing. The world being as big as it is, you're _probably_ not the first person to think of this particular idea, and it's _usually_ that there's not a market for it.
That said, maybe this is an idea you can niche _up_ with? Instead of just one form of moderation, could you take the basic tech and use it to moderate a whole bunch of nasties that admins don't want to waste time dealing with? You'll want to make sure that the a _paying_ market exists for such tools first, obviously, but it's a potential option.
Agree. A one off tool that detects pirated links seems odd to pay for.
Either a monolithic tool for handling moderation automation in general seems good, or better yet a marketplace where I can buy automation plugins for Discord in general, both for moderation as well as other administrative or entertainment tasks.
It's easy nowadays to throw up a quick slash page with some SEO friendly pages to gauge market demand. Have an email wait list and if it gets large, you'll conveniently have the email of your first clients.
