A scammer on discord.

I see a scammer with username: ttin7 (backup id: ttin5) on discord. He sell nitros, and another stuff not genuine. He sell with a cheaper price, and he scammed a lot of people on discord.

His discord server: discord.gg/ttinshop
I want to report him as an scammer, I don't want more people get scam. I know buy nitro from this guy or other who are selling nitro with a cheaper price may be got scammed, so from now I will buy from discord. 
I believe that discord will make this social more fresh.
