Some option values get detected as a bot

When I use some random option values, I sometimes get detected as a bot by https://fingerprint.com/products/bot-detection/ . What is causing this exactly? And what random values do I need to avoid in order to evade detection?

Thank you!

Here is an example of option values getting detected as a bot by https://fingerprint.com/products/bot-detection/

In fact, about 80% of the options I test randomly are being detected.

Has anyone found the reason for the detection?

I guess that some values together are invalid…. Which ones? I don’t know.

Yeah, it seems that some values are not passing the checks properly, most probably they dont fit together, will post an update here when I investigate
