I trade with friends only, pretty much. So I love it. I've gotten most of my stranges that way, and have given a few away myself. I gave a Botkiller Scattergun to a friend two days ago, as I already had one. And just yesterday, a friend gave me a Strange Powerjack. What's not to love? If people trade spam, it's up to the server admins to act on it. I definitely don't tolerate trade spamming on our servers (you can do it, but don't spam the chat. And make it snappy. You'll get kicked if you idle for too long anyway).
