Pingo Pongo is a bot designed to ping everyone in the server and delete the ping, everytime someone sends a message! - Zerrain3/PingoPongo
Its Intended For Servers Which Are Meant To Be Groups. Since Discord Has A 10 Member Limit For Groups, Its hard for some people to live with it :D
If your too lazy and just want to do it in 3 simple clicks you can invite the Original Pingo Pongo!
