TS is trolling everyone in serious /k.

99.9% sure but still considering to hire them. So you're either:

1. Cheapskate
2. Incompetent
3. Desperate
4. All of the above

... then proceeds to laugh at himself.

So you've just confirmed that you're a cheapskate who's incompetent in his job in the hiring process and is now desperate to hire 2 candidates whom you ASSUMED lied about their previous salary.

Summary - you just want to be a moral police by digging their private information through illegal means for your own self gratification.
