Coming from other engines and Stack Overflow, IMHO Q&A should be more rigorous than the forums. I'm not saying it should be as scrupulous as SO, but still preserve the decency and respect rules of common sense like: search existing question before posting your own, avoid double posting, not answering own/other's questions with a comment etc.
But ads?! This is unbelievable. I saw one myself from "michaelsullivan" posted 5 hours ago...
