Some people engage in scam baiting, which is intentionally wasting time of scammers so that said scammers aren't spending their time actually scamming real victims.

Is this allowed? It involves a lot of deception, and may be considered bittul zman. There will likely also be a Jewish take on how one should treat them even though they are a scammer.

Not sure what else could be related, but it would be interesting to see answers to whether scam baiting is allowed.

  • There also is likely a difference between a Jewish and non-Jewish scammer

    Why would you think preventing a thief from stealing from others would be prohibited? Lo Taamod al Dam Re'echa.

  • @Loani Would we treat the Jewish scammer better or worse? Why? That sounds far fetched. How does one tell if the scammer is Jewish or not?

    It is forbidden to deceive anyone - Jew or Gentile - even if he doesn’t cause a financial loss (Chulin 94a)

It's permitted for tzaddikim to out-swindle swindlers.

שרי להו לצדיקייא לסגואי ברמאותא עם רמאי

    Bava Basra 123a and M'gilla 13b: אמרה ליה ומי שרי לצדיקי לסגויי ברמיותא אמר לה אין עם נבר תתבר ועם עקש תתפל ("[Rachel] said to [Ya'akov], 'My father is a swindler, and you will not prevail against him.' [Ya'akov] said to her, 'I am his brother in deceit.' She said to him, 'But is it permitted for a righteous person to engage in deceit?' [Ya'akov] said to her, 'Yes. "With the pure you [shall] behave purely, and against the crooked you [shall] behave with cunning (II Sh'mu'el 22:27)."'")

  • Thanks, and thanks @Fred. Is one allowed to go out of one's way to do this? How much time should one spend on a scam-bait session? Accustoming oneself to deception is fraught with danger to one's personality and soul, so a little more detail would be welcome

  • @RabbiKaii Idk but I'd just focus on the be a tzaddik part. That is, do what is right per your devotions, hitboddedut etc. And that's not hard; Rabbi Nachman said, I can make you into guter Yidden, even complete tzaddikim. Just do what's right = tzaddik? Actually I would advise aim higher and be a Hasid, and say Na Nach Nachma Nachman with simple faith. Commented Nov 27, 2023 at 19:19
  • @RabbiKaii I don't know if you are directing this question to me or not, but my point was not to justify scam-baiting specifically, but merely to source the general principle expressed in the answer that it is permitted to use dishonest means to thwart the scam of a crook who is wrongly using dishonest means against you. Of course, even in the rare circumstances when dishonesty is permitted, it should only be used as a last resort when there is no other recourse.

    @RabbiKaii I seem to recall something along those lines, as well, but I don't recall a source offhand. Although Sanhedrin 97a is also an interesting source that brings the story about Rav Tavus or Rav Tavyomi who travelled to a place called Kushta (meaning "Truth" in Aramaic) where the residents were scrupulous about honesty. Rav Tavus/Tavyomi was an especially honest person, and he settled in that place. One day, he told a lie for a legitimate reason, and nevertheless he suffered for this and was expelled from Kushta.
