Hey guys,

I’m planning on adding some “free tools” to my site but I know they’re going to get abused by random bots or malicious users and want to restrict access to a reasonable number of executions (say X per hour or something).

Thing is, I’m trying to find a reasonable way to identify the user without relying on cookies or IP address, etc as these are all easily ignored. Are there any good standardized fingerprint libraries you know of that can help with that? Would appreciate any recommendations you might have.

Thanks
