You're Running A Radio Station Not A Jukebox
They wanted to limit the amount of requests a user can request.
You can limit the time between requests and also control how many songs someone can request per day.
While it's nice to have the request function in RadioDJ you have to remember you're running a radio station not a Jukebox.
You control this with most of the Demo Request Scripts on the forums.
A daily limit on requests (E.G: No more than 5 requests from 1 IP per day) is better than allowing so many requests per hour.
Remember: YOU don't have to play a request that someone has made.
It's just that a request...
Requests from listeners are good but treating your station like a Jukebox isn't going to win you many regular listeners.
If people email or contact you on social media to complain that you're not playing their requests.
Just Ignore them it's your station & it's up to you to decide what gets played & what doesn't.
If you just have listener request after listener request you might as well call your station The World's Biggest Jukebox
The less your stream sounds like a Jukebox the better it will be for your core base of listeners.
Internet Radio is supposed be creative and entertaining.
