Is there a bible quote for my friends?

[Jonathan Alexander]

Romans 2:1-3 is good for judgemental people and hypocrites

You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge another, you are condemning yourself, because you who pass judgment do the same things. Now we know that God’s judgment against those who do such things is based on truth. So when you, a mere human being, pass judgment on them and yet do the same things, do you think you will escape God’s judgment?

But just stick them in to the authorities if their boasting about it online. You won't even have to give your name or testimony in court either.
