I know it's easy!! I just looked around both my ecency app and peakd and couldn't find it. But I've seen it a bunch of times, it's called a 'burn button' if I'm not mistaken but I'm guilty of never trying it I guess. Sorry I can't be more help.
In my opinion, I think an article that addresses issues on the blockchain deserves to be rewarded. Just sayin.
Good morning Sweed!
