It lets you easily route your Discord server invites through a controlled page with a captcha. It generates a unique, time limited one time invite for every user. Thanks to this, you can stop most bots from entering your server.
This way you can send users to a subdomain like:
https://yourcoolproject.xyz/discord
or
https://discord.yourcoolproject.xyz
Users complete the captcha in web browser rather than in Discord. One issue with the Captcha biot Once the captcha is complete, it offers a 1 time use invite link, so it’s not possible for bots to spam and reuse it.
Also, with generic or vanity invite links, those are reusable and spamable, even if you have captcha built within the Discord server. Once the spammer has an invite to the server, they are able to get a member list of all the users in your server, and are able to scrape and spam your entire server, regardless of if they pass captcha or not.
