It is genius. As a "startup", for free you are getting community, traffic, marketing and terabytes of free image hosting.

Plus think of it this way, websites fight tooth and nail to stay relevant to the user. You win that fight if they "install" your app. Joining their Discord server means you have installed their application to one of the most frequented messaging apps. If this was a website, you would have forgotten about it after couple uses. At least when it is in your discord server dock, it is visible to the user and in their mind.
