But if nobody complained and the lemons are getting paid for, I wonder if anyone would try to stop you doing this 7.5 times a day and how long it'd take.

If you're looking for government or police intervention, the answer is that it would never happen. They don't give a shit. I was subjected to actual stalking and harassment for an extended period of time (years) from my ex and people affiliated with her, and the police were absolutely worthless.
