Deleting tables when plugin is uninstalled

I googled some examples. Best one I came across: https://wpengineer.com/35/wordpress-plugin-deinstall-data-automatically/

Please keep in mind that removing data when uninstalling a public plugin is highly unusual.

Thanks that a great tutorial!

The plugin stores a lot of data like IP addresses, I think it’s a good idea to delete that excess data if someone doesn’t need it anymore
