Is the ascii format not enough?
I do the same on all my sites. On most sites this has worked quite well...HOWEVER, I did this on a Chinese site that went up about a year ago and have seen no end of Chinese spam to the main contact address. I'm not sure if these guys are hand adding me to Chinese spam lists, but I'm pretty sure I've been harvested by a bot. I changed the address a few months ago and almost immediately got spam (within a few days). I can't prove it, but it seems that the ASCII trick isn't enough for the determined bots any longer.
