Discord Ban Appeals

This is a form that allows users to appeal their bans from a Discord server.

By using OAuth2, it ensures users can't forge or fake appeals.

How do I use this?

1. Create an application on the Discord Developer Portal.

2. In the Bot section of the newly created application's dashboard, create a bot account and invite it to your server with the Ban Members permission.

   Pro tip: Use the URL generator under the OAuth2 section of the Developer Portal dashboard for your application to generate the invite link. Make sure to select the bot scope!

3. In your server, create a channel dedicated to ban appeals. Ensure only mods and the bot can view the channel, and that the bot has the Send Messages and Embed Links permissions for this channel.
   

4. In Discord's settings, go to the Advanced section and enable Developer Mode. You will need it soon.
   

5. Click this button:
   

6. In the web page that shows, login to your GitHub, GitLab or Bitbucket account. Create a repo for your form with your name of choice, then fill in these environment variables:

   Variable Name	Instructions
   DISCORD_CLIENT_ID	Copy it from the OAuth2 section of your application in the Developer Portal.
   DISCORD_CLIENT_SECRET	Copy it from the OAuth2 section of your application in the Developer Portal.
   DISCORD_BOT_TOKEN	Copy it from the Bot section of your application in the Developer Portal.
   DISCORD_PUBLIC_KEY	Copy it from the General Information section of your application in the Developer Portal.
   GUILD_ID	This is where the developer mode you enabled in step 4 comes in handy. Right click your server icon and press Copy ID.
   APPEALS_CHANNEL	Same deal as the guild ID, but with the channel you created in step 3.
   JWT_SECRET	Use a password manager to generate a password with ~50 characters, or mash your keyboard.

7. Login to the Vercel dashboard and go to the Settings tab for your site.

8. Click Domains and edit the Production domain to something unique, or setup a custom domain.

9. Go back to the Discord Developer Portal, open the dashboard for the application you created in step 1.

10. Click on Interactions Endpoint URL and enter https://[site-name].vercel.app/api/interactions, replacing [site-name] by the name you picked in step 8 (or the entire Vercel domain by your own domain, if you opted for that).

11. Hit the green Save Changes button.

12. Go to the OAuth2 section, click on Add Redirect and enter the same URL as in step 10, except with /api/oauth-callback instead of /api/interactions/.

13. Again, click the Save Changes button.

14. You should be good to go! You might want to test if it works as intended with an alt account, and if you encounter any problems feel free to create an issue on GitHub.

Blocking users

Users that spam requests can be blocked by creating an environment variable called BLOCKED_USERS, which should contain a comma-separated list of user IDs. To do this:

1. On your Vercel dashboard, go to the project with your site, go to the Settings tab and click Environment Variables.

2. Right click on any mention of the user you want to block, and click Copy ID. You need Developer mode enabled for this option to show up, see instructions above.

3. Under the Add New section, set the Name to BLOCKED_USERS and the Value to the user ID you just copied.

4. Click Add.

5. Go to the Deployments tab, click the ⋮ next to the topmost item in the list, then click Redeploy. Check 'Redeploy with existing Build Cache', then click Redeploy.

6. To add more IDs, repeat step 1 and 2, scroll down until the list of variables in Vercel's dashboard, click the ⋮ next to BLOCKED_USERS and click Edit. Add a comma after the existing value, paste in the copied ID and click Save. Redeploy the site as in step 5.
