Rickroll Detector is a simple bot that detects rickrolls in messages and warns users if there is a rickroll.
Commands: r!commands, r!help, r!invite, r!botinfo, r!report, as well as owner commands.
This bot currently only detects YouTube/video URLs. If you find a rickroll that is not detected by the bot, report it using the command r!report (url). Abuse of this command will result in a blacklist from it.
