Hey Alex, this definitely sounds like a miss on our part, so apologies.
As you know, we're fans of uws and not including the original license was a screw-up in our automation. We're working on fixing it and immediately releasing it with the proper license. I've also asked support to follow up with you directly in case there are further issues.
For the contact, either opening an issue on one of our repos or emailing our legal team (abuse@discordapp.com) would have been guaranteed to get you an accurate response. Unfortunately the verbiage you used in the email is very similar to that used in other support tickets we get for our API, and our team (as they did in your case) forwards users on to our API chat which can provide more in-depth/advanced support.
