"Don't spam. Spam includes off-topic messages, messages in other languages besides English, messages in "ALL CAPS", messages with repeating characters, advertisements, and any messages that you post several times in a row and/or on several places."

Bold for emphasis. It doesn't say "Spam includes (...) advertisements that you post several times"; it just says "advertisements".
