> I'll engage and disengage randomly, so no one knows what works.

Any predictable pattern, including when you disengage, is just another feature for the pricing model. If the model learns you reliably leave after 3 hours, it will simply front-load the surge pricing into that initial window.

  Analysis: This user loses disengages during 75% of the
  time and belongs to a group of 5% who do the same. The
  expected revenue for this group over a longer period
  and with multiple users is 24% lower than for the
  average user.

  Action: Since 80% of theirs engagements last for at
  least 12 hours, ads should be shown and prices
  increased only within the first three hours.

Hope this helps :)

At which point the user disengages from the platform permanently. Great work.

He said randomly, which means the opposite of predictable or reliable. Sometimes he won't disengage for years and the algorithm would be non the wiser!
