I definitely got so wrapped up in searching for images for my game that I didn't think until afterwards about the fact that I was searching for "children prisoner sweatshop."
I believe the proper way to signal to the government monitors that you're just a nerd and not a serial killer is to simply add "5e” to the end of the search qiery (or whatever other edition or game system you're using). Because people involved in cyber monitoring are all nerds too so they'll recognize the lingo. Heck, if your search looks interesting enough they might even make up an alias and ask to join your game.
I was facing a weird vampire dragon lord that was projecting and using his blood as a weapon and shield. He was in the process of using it to suffocate the party. In a fit of desperation, I googled "percent of water that makes up blood" and after seeing it was sufficiently high, I presented this prompt to the DM:
SO: we all know that blood is mostly water. In fact, it's x% of it (can't quite remember the amount...) So with that, I said I cast create or destroy water at 4th level to destroy 40 gallons of water from the blood
DM lets me, then says he has to roll some dice.
After a considerable amount of dice rolling sounds, he announces that the entire left side of the vampire went limp, and he fell out of the sky, dying rapidly. I saved the party by destroying some water as a 17th level encounter.
