Maybe post your sim and coordinates so that if a bot owner comes across this post maybe they can configure their bot to not land on your land.
Messaging some bots does no good but but Ive noticed some leave contact details, you could try to message them or the owner if listed to stop them.
Easiest solution is just just ban them from your parcel, thats why we have the tools to handle these type of things ourselves without having to submit tickets because a bot landing on your land isn't breaking any rules, chances are the owner of the bot is unaware that its bothering you and can fix it to not bother you by re-routing it or... just ban it!
I used to rent a parcel on Nautilus - Melqart and I swear to you it got visited by 35-40 bots a day (I used to have a list of them all). I ended up turning damage on and put a collidable prim with a Damage 100 script in it where they would fly up and kill themselves (Because all of them would land and fly up 3-5m) lol.
My current home gets visited by 10-15 bots a day. I don't mind them though after I took the time to learn about them, I know they are bots and they aren't doing harm. Most just collect data like parcel information or avatar information, height, age, parcel names, sizes, etc etc.
