My one little thing I do is when tightening an accessory I always leave the screw horizontal or vertically. Just so I know if anyone has removed it.
My first boss told me to do it. Not that helpful but something I've stuck with.
I was also taught this, There are several reasons behind it.
1) It looks professional
2) If left vertically and the screw is outside the water runs through it and does not sit on it.
3) Tamper proofing like you say.
Its called a tear drop
