Spamtastic

So I opened up my e-mail today and, by reflex, went to go clear my spam folder. In the 5 seconds it took to do that I happened to notice that a large portion of the junk mail was composed entirely in either Japanese, Chinese, or Korean. My question is, which is less effective: Japanese Kanji spam or English erectile dysfunction and penny stock pump-and-dump spam? The fact that both are profitable enough to keep spammers in business is pretty disheartening—that's a lot of suckers born in a lot of minutes.
