Around 2000 there was a dial-up service called Juno. It took about 15% of your screen to show a rotating banner ad and had some time limit for use. As far as I recall every restriction was implemented in the client.
As such there was a really easy workaround to connect directly without using their software and bypass every restriction.
A guy I know used that workaround and at some point got a letter in the mail from them because he was in the top 1% of users of the service which was very costly to them so they terminated the account.
My hunch is even small scale abuse of a system can have a big effect. Even if it seems small it still might be impactful.
