Add-on A fingerprint plugin to discover different accounts of the same person

[urivil]

I understand that there are various plugins that do this.
I just came across this plugin [https://xenforo.com/community/resources/021-multi-account-detector.7623/]
Are there different plugins for this purpose, and which one is the most recommended?
Thanks!
