When is ‘Enough’?

The news today is that the number of Windows botnets has tripled this month. This isn’t terribly surprising news, but this kind of growth can only go on so long before the Commons is completely bare and muddy. I already spend $50 a month in computing resources to handle the spam for the small number of accounts I host, and my blog got overrun with 3800 spams recently (AJAX-comments are apparently now handled).

When do we say, “Enough?” And what does saying that look like?
