At my old place of work I use to quite regularly parse PDF and PS files
for text. Not so easy on encrypted files or those PDF's from scans!

Would a spammer think its worthwhile? I mean they could also OCR the
image files on a website. They would only need to look for an "@" sign
and all would be revealed. I am sure they'll start doing this when the
current harvest starts going downhill!

Can web spiders read and harvest e-mail addresses from a pdf file ?
