Script to delete discord messages in a channel based on user id

README

This is not really perfect to use and has the risk to ban you based on discord TOS on automation.
s : server id
c : channel id
a : user id
m : id of message to start from 
You also need to fill in "x-super-properties" and "authorization" with your datas.
Good luck :)
