Giant in the Playground
Giant in the Playground is a website and forum run by insane douchebags who like to hallucinate nonexistent rules violations into people's posts while selectively ignoring actual trolling. It is best avoided at all costs by anyone who wants to engage in serious discussion about anything. In one of their more stunning acts of stupidity, a user was issued an infraction for saying that the planets of the solar system were named after Greco-Roman deities, as examples of proper nouns in a discussion about grammar, because this was allegedly a violation of the rule against discussing real-world politics and religion. But another user straight-up said "capitalism is evil" and that was just fine.
As usual, the only place for fair and honest discussion of tabletop gaming is the /tg/ board on 4chan.
