> But will they behave like same user in past? I would guess there is lot of difference between how bot accesses page and real user has historically accessed them. Like opening multiple tabs at one time, possibly how long going through next set takes. How they navigate and so on.

That would be making an assumption that a device and/or account maps 1:1 to a specific human. It does not. People share accounts, share devices, and ask others for one-off help ("hey can you finish buying this for me while I deal with $[whatever our kid just did]", this kind of stuff).
