IDK what it would do. Cannot be sure about that. But I don`t think there are a lot of people that are stupid enough to post sincerely spammy messages in a thread with "NO SPAM ALLOWED" in title, you know.
Unless of course, they are completely new to the concept of spammy posts in a conversation thread.
You`re right. Double-think before you post.
The most important lesson many newbies learn the hard way.
But anyway, don`t be too picky and don`t be too harsh on newcomers. There are different opinions, and the thing you think is spam might be a normal message for a newbie. I hope you get what I mean, lol...
Of course, that's why I'm here. Then again, some of the vets do try to help in the guise of harshness; at the same time it works as a test of maturity: if you can take jokes and sarcasm, you're mature enough to avoid spamming (at least frequently).
It's a long and shaky road for them but they'll pull through. (most of the time)
