That’s quite a cute “Chiddush” of yours, that someone who is not sure if it’s true or not is automatically being motzi shem ra, even if it turns out it was true. I don’t think that’s the case. If you’re so sure, kindly back it up – I’d like to know.

L’toeles in itself does not make it permissible, there needs to be 5 – 7 conditions met.
