Add the option to block calls!

I can't express this enough. I've received so many accidental video calls and regular calls from dozens of people and I can't hesitate enough, please add an option to decline all incoming calls. I know that it's fairly simple to just decline a call, but on mobile due to the video call option being awfully close to the rest of the buttons its extremely easy to start a video call with whoever you're calling with. I've disabled Discord's camera access and somehow still managed to get accidental video call from my L/O. 

It would be nice!
