I believe, that as smell, you mean it is very unpleasant, and not a deadly chemical like poison or gas.
No. An Irritating smell can't kill you. The smell will 'get used' to the person, and the person will start ignoring the smell. If there is a smell of rotten flesh nearby, it may make you sick from the disgusting smell, but that is because biologically we tend to try to stay away from harmful chemicals and bad things. So no, I don't think that anyone should be able to die by smell.
I believe that yes, any debate topic should be allowed on this website, except a few motions. But before that, let me define spam.
Spam: irrelevant or unsolicited messages sent over the Internet, typically to large numbers of users, for advertising, phishing, spreading malware, etc.
I believe that we should always be able to monitor what goes on this website because anything that is unmonitored is a recipe for disaster. We are humans. People are evil. You can't just let anyone post anything. There may be incredibly disrespectful, pointless, useless motions that only would hurt and cause harm to our community. So Yes, we should be able to remove the spam messages, because there is no value in a post of spam, and there is whatsoever, no use of a message that contains spam at all.
Finally, I would like to end this debate with an analogy. Imagine you have a voting poll, and anyone can post anything. Some man keeps on advertising his products completely irrelevant to the actual use of the poll. Spam causes a lot of time wasted in filtering the messages, and overall annoying-ness. So in that way, no, spam should not be allowed on this website!
