If you use a hard hash function you cannot brute force that on a laptop - not even a tenth of that. You can, however, spin up compute instances to brute force it in a few days if you have $50k lying around.

What are the odds that a website will run a computationally hard hash function on every single HTTP request just so it can log something less sensitive than an IP address?
