You could fix the mechanic rather than discarding it entirely. Adding in-game captcha would go too far, but having a resource cost, having a cooldown on the charter stone/portico used to travel from (and of course not allowing whole rows of porticoes to be built together in a small area, or having the cooldown also apply to other porticoes within a certain range), making the guess take a significant amount of time, or some other measure to make it too costly or too slow to be feasible would also work.
