However if she made it clear what she thought about this then him not stopping could just as well pass for harassment.
I actually went ahead and researched this as a point of curiosity, and it looks like that wouldn't actually work as a charge. In order for something to count as harassment, you need to do it to a person or group specifically, repeatedly, intentionally with your actions not serving some legitimate goal or purpose.
The distinction on that last one, I think, is the idea that those high pitched bleeping things they attach to doors in some places are annoying (duh), targeted at a group (mallgoers), repeated (every time the door is opened), intentionally annoying (that's how they work), BUT they serve purpose outside the annoyance of humans (scare away pigeons). So even though those beepers fulfill almost all of the criteria, they don't count as harassment because they provide a legitimate and intentional service to the mall and mallgoers.
So although the 'beachgoers' could be considered a group, we would need some sort of proof that the boy had flown his drone with the purpose of being intentionally annoying and for no other reason multiple times before it actually counts as harassment. Even if we construed continuing his actions despite requests to the contrary in the same day/hour as 'multiple', his landscape filming and the lack of other noted complaints from the group 'beachgoers' implies that not only did he have a legitimate purpose outside of being annoying, but he wasn't being all that annoying.
An extra note here - it seems that if you are suspected of attempting to harass a group, then most of-or a recognized spokesperson for-the group needs to complain about it. One person can't name them self spokesperson unilaterally and make demands or claim harassment on behalf of a group with their prior OK. This is interesting because while you could accuse this kid of repeated annoyance of the group of beachgoers pretty easily (he was in the area many days in a row doing stuff), it wouldn't work that way for an individual person. You would need proof that the person was attempting to target you specifically, while the automatic defense to that is "I come to this beach to film scenery even when that person isn't here" or for the more overt pervert "I film topless women here whether or not she shows up".
