[SomeoneCares11]

Hi,

i have spoke with abal about this issue, i produced this issue on 2 servers

Server 1:

Host: OVH
Os: Debian 9.3 Stretch (stable)
Node v8.9.4

Server 2 :

Host: OVH
Os: Windows 2012 R2
Node v7.5.0

How to produce ?

1- Create simple bot with ping pong
2- Spam the bot with (ping) from 3 accounts, until you get ratelimit and negative avg ping

after that you'll get many unexpected ratelimited, and may discord ban you if you hit global.
