keep blinds shut/windows locked. Doors too. I dont want to seem callous or flippant but have you had any breakups recently that went south? Any hookups that maybe went bad? Any negative interactions w strangers recently? Stalkers?

No there’s no possibilities like that.

The only other possibility that’s running through my mind is that it’s police scoping out a polytunnel we have. It’s possible that someone has told the police we’re growing weed, but it’s actually full of palm trees I’ve been growing for several years now.

Depending upon your location, it may be against rules laid out by whatever agency has authority over flights/flying in the country you live in.

It’s UK, I have no idea what the laws are tbh.

Bird netting or fishing line strung back n forth might foul up a rotor.

This is actually pretty viable, maybe some fishing line run from ground to nearby trees. Wouldn’t interfere with anything on the ground for people using the area but if you tried to fly something in there it would catch on something.
