Shooting/Bumping users in infiltration suits?

[powdahound]

Lets say I'm in an infil suit totally cloaked over in the corner. What is there to stop a defender in the base from just randomly shooting around until they see that their bullets are hitting something? Seems like if I were a defender I'd either go walking around all the crates and by all the corners seeing if I bumped into anyone or just shoot into the areas to see if I'd hit anything... Does this seem like an easy way to find hiding hackers to anybody else?
