Scientific spam

I get an enormous amount of scientific spam. There are the obligitory emails to attend conferences in China to give talks on topics I don't work on, and endless spam from new online journals inviting me to submit my research on equally obscure topics (why yes, of course I will consider the Online Journal of Mycology for my next submission). Then there are the companies that spam you to make knockout mice or antibodies against any gene you have published on. It is all harvested from papers automatically, and very poorly at that - this company even mixed up the author name and gene name in their spam generation!
