I've had a few issues on my site with blocked users coming back and spamming the site. IP blocking is simply not enough as IPs can change quite regularly, or you can use proxies.

Are there any other methods to stop this sort of spamming? I thought maybe when a banned user visits Q2A could log a cookie (or one of the many other tracking devices like localstorage) so when they return on a different IP, the site still knows they are banned.

No. I was already blocking users but that does nothing to stop them registering again.
