Assuming that there's a trust being built between users, far more dangerous results can happen than 'nigerian scam' posts. That's the problem with minimizing security: you're making it so that there can't (or shouldn't) be trust between users because there's no reliable way to know who is making the post. "Hey, just a quick note to let you know I tried <apple app link> and I love it! Grab it now!" Or, more dangerously, someone could post a phishing link and because the context is different, people's trained safeguards ("BE WARY OF E-MAIL!") aren't as wary to blog links. So yes, there are sometimes tradeoffs between security and ease of use. But I think trust is more important to posterous than you credit.
