I (a Jew) generally abhor the ADL and friends' behavior in public, but in this case I hope strongly for a typo. Figuring the best approach is to offer the poster the chance to present something plausible.
The two main Jewish populations in France are Sephardim and Askenazim. Both have associated stereotypes that are widely used in French Jewish humour. Sephardim are regularly portrayed as extravagant pokers player, huslters and show businessman.
A good example of this stereotype is the film series "La vérité si je mens", "Would I Lie to You?" https://www.imdb.com/title/tt0120471/r.
Marco Mouly is a poker player, huslter, fraudster, compulsive liar and many other thing. Even in a film or a standup he would be too much to be true.
Those are the two major Jewish populations... everywhere.
I know things are different in France, but in the States the rule is generally that "only the fat kid gets to make fat jokes", and making comments like "caricatures of sephard" is in extremely poor taste.
France is also a tragicomically racist country, so "where I'm from" doesn't exactly cut the mustard for enlightened commentary.
Just because we control the media doesn't mean that you can make jokes about it (and this is an example of the Jew telling Jew jokes).
