LEV578 "You shall rebuke your neighbor" If someone begins to tell you loshon hora, and instead of rebuking him you assist him by listening to his narrative, you violate this commandment. It is important to remember that rebuke should be administered as soon as you realize that the narrative contains loshon hora. Do not wait until the other person finishes speaking. Every single word of loshon hora is a separate transgression, and it is your obligation to stop the other person from sinning.
