If someone asks something, you go there and answer him. If multiple people ask something, you answer all of them in a single post.
The abuse is possible when we make the thread show up at the top of the board every time someone posts there. If people with bump scores post there, it bumps. This avoids people creating fake accounts to ask random generic questions. Yes, this affect legitimate users, but what can we do when people can just shill their scam products to the top when there isn't any limitations?
