I installed MM-email2image (http://wordpress.org/extend/plugins/mm-email2image/) to "protect" email addresses, etc., from being auto-scraped off my blog (http://MarkKurowski.com).
It works wonderfully, creating a tiny image from a text string. But here's the problem: it does it "live" instead of beforehand. So the page source contains the actual text string!
So, web experts out there, don't the bots scrape the source of the page? It's clever that humans won't be able to select the text (because it's an image), but it seems useless against automated scrapers, no?
