When a suspected kikeposter replies to your post or comment, first, try dialectic. Attempt to open a dialogue in the direction of truth and mutual understanding. You don't have to be nice, but do try to exchange ideas. A kikeposter will not engage honestly. They use pilpul, not dialectic. They will insult and nitpick and accuse. They may call you a kike. They will certainly try to turn any disagreement into division. Once you're confident they're a kike, apply the litmus test: WILL THEY DESECRATE JEWISHNESS? Kikes refuse. It's one of their religious rules or something? Dip Moses in feces, point out the ways Solomon was utterly unwise - "and that's the wisest jew that ever lived!" The prophet Elijah was born from demon vomit. Say how Noah should have killed Shem, the most wicked of his sons (aka actual anti-Shemitism). The specifics don't matter. If someone uses pilpul and refuses to desecrate jewishness, they're a goddamn kike.
