Do you used the current date/time and/or Math.random() to generate your random URLs client-side?

I left Google's indexing system 10 years ago, but back then, I made some inelegant workarounds to prevent these features from breaking duplicate page detection. I'm nearly certain the code I wrote has all been replaced with something Chrome-based, but I'm just trying to think of things that could trip up page analysis.

I could see how very rare patterns that are typically used to intentionally trip up page analysis might put your pages on some bad actor list. I really have very little idea how these auto-detection systems are implemented, and these are wild guesses, but they're hopefully better than nothing.
