Isn't this is like free promotion?

I don't know I have set the right topic but so everyone knows that when you go to the join page discord shows some example invite/venity links and there's a link "cool-people" that's works I mean it exist and redirect to a server isn't the examples links should not be usable? probably it's a bug or something because I have never see that link working before but it working at this time and this is not just a simple bug or anything whatever it is called I'm not so good in english but it's like discord promoting a server but the server is dosen't giving anything back for that sorry if you don't understand something as i already said above that my english is not good
