This is a url link checking bot.
When a user posts a url in the discord server , the bot checks if the url has a valid domain , a valid domain is any url which is allowed by the admin. If it finds a invalid link , It deletes the post and assigns an ID for further purpose. If a user feels the he/she posted a valid url , he can request the moderators or admins of the server to validate the url with the help of ID. Once the url is validated and the admin/mod feels it is valid they can approve the url with ID. Once approved, the url will be added to valid domains.
you can access the bot help using ' clink.help '
