Skype did the exact same thing long before Discord and backpedaled FAST from it. Here's the problem: Currently Discord is BIG PUSHY in having people buy Nitro. Try to use a greyed emote (even if said greyed emote is already grey anyways), get pushed. See the gift box in the text box? It's a trap! Push'd. Open Discord? OwO Niwtwo wanna be fwiends, get pwshed! Check your Settings? DISCORD NITRO IS FREAKING HIGHLIGHTED AS IF SAYING "LOOK AT ME!"
See the problem here? No? Well: Not everyone can buy Nitro, and not everyone wants to buy Nitro, and pushing it so hard will only make them want EVEN LESS.
So, how to solve?
Simple: New Appearance Setting:
"Hide Nitro Promotions"
"We are sorry to inconvenience you with so many offers and we won't bother you again about it."
Nitro Boosting can stay, since it's like... Really off the way.
