As a thought exercise, could it be captured?

Join the referral program for a low cost online pharmacy. Post a link on each platform informing the users about the availability of male health products. Measure if it gets removed.

Depends on the platform. On Reddit, definitely yes, as almost all censorship is "deletion style" where the target post or comment is initially visible until the mods suppress it.

But your point is well taken, it's definitely more challenging and expensive than what's being done here.
