JWE does bring up a good point. Spam is always going to be present. I don't mind people posting the spam they find on my profile as long as they do it in a manner that will make it easy for me to navigate. So, if you do catch spam please organize it like this:
-The URL of the user spamming
-The URL of where they are spamming (if it is on page 2 of free rider, then send me page two of free rider)
-Continue to list all the URLs that you have found the spam.
If you find someone spamming in the chat, then simply leave a URL to their profile.
Also the best way to help us with spam is if it is on your profile DELETE IT! Don't let it sit there. It is not your responsibility to warn or argue back with the spammer. All you need to do is inform a mod and give us the URL of their profile.
