Doing that to annoy devs who didn't sanitize their database inputs is like walking along parking lot just to see if anyone has forgotten to lock their car, just to put a post it in the steering wheel.
Nah man, not sanitizing Inputs could pose serious security risks as someone could use this shit to escape and run arbitrary database queries potentially leaking passwords or other info or just wiping it
(Afa I have learnt on the internet)
Just like @Norgur@kbin.social said, leaving your car unlocked is a serious security issue and you'd be lucky if someone walked by and just left a post-it note
