ANTIRAID.GG
Check out the home page for the full Discord Bot List.
Anti-Raid protects your server against malicious bots and raids before they happen. The bot has a simple setup process, with only the most important anti-raid commands included, such as !ban and !lockdown. All the available commands can be shown by typing !help.
We are soon planning on launching a support server, and a website with more information. Invite the bot today at https://antiraid.gg
