Before a bunch of frum Jews get our forum locked for acting immaturely, let's all relax here. No need to get out of hand by other typing loshon hara or accusing others of it. sam33, the burden of proof is not on zvika here to prove his hechsher. This isn't a kosher forum. If the 2 of you disagree about what his real hechsher is, whether it's acceptable..., PM each other and discuss, and eat and celebrate! But don't both of you start making accusations of loshon hara, libel... against one another please.
Keeping kosher is one of the commandments in the Torah; another one is to treat all Jews wit respect. Let's try to remember that as we try to remember what the purpose of kashrut is; (G-d's will), and therefore should NEVER be the cause of chilul Hashem and fights!
