The one rule that keeps you un-banned
Across every community here, the pattern is the same: be the most useful answer, not an ad.Lead with help, disclose when you mention your own product, and save launches for the designated promo threads. The fastest way to torch a new account is dropping your link in a top-level post. Reddit's spam filter and the mods both punish it.
