Going past page 1 of SERPs is discouraged or even prevented in recent times, all focus is on "the top result",^2 and some www search engines actively try to block exhaustive research and discovery. By continuing searches over time, e.g., page 1 of results on day 1, page 2 on day 2, page 3 on day 5, etc., one can sometimes avoid being blocked when doing exhaustive searches. > > 1.

How can I get more details about these filters. Are there existing implementations somewhere online which I can test? Seems pretty interesting.

Note there are some web search engines that only block exhaustive searching when the computer user is not "signed in". This could be a coincidence, not an attempt to force computer users into submitting to increased surveillance and data collection foor coommerciall purposes. 0x is written for a computer user who did not "sign in" to websites in the 90s, 00s, 10s and as a matter of habit does not do so today.
