Song Request Issue

I want my users to be able to do song requests but when they do !songrequest (Youtube link)
It times out the non mods, however I don’t want to make it so you can post links in my chat.

Is there a way to allow links for song requests but at the same time not allow other links.

If you are not using the Nightbot Beta, you should upgrade to it: https://beta.nightbot.tv. When using the Nightbot Beta, YouTube and SoundCloud links are automatically whitelisted when song requests are enabled.
