While most people report that "granny was a wonderful cook," the reality is that they learned to like (and expect) whatever mess the old lady fed them.

A similar effect applies to advertisement, and especially to government propaganda.

A fairly extensive article on SPAMMER techniques was previously linked in another thread here, and affirmed that most internet SPAM is deliberately made to appear "slightly illiterate."

While sending thousands of emails is pretty cheap, the Spammers have to track all the responses and often prepare individual followup responses to the likely replies, which is time consuming and hence "expensive" for them. They assume that those smart enough to recognize bad grammar are unlikely to stick with them long enough to get any payoff, while anyone who replies to a stupid SPAM is sufficiently stupid to be a better target. Stupidity is fairly common.
