As an experiment to see how quickly a published e-mail address attracts spam, I created an e-mail account on a domain I own and placed it on the homepage two blogs I own in July, one of which does not use the http:BL service. I added code to the CSS file to hide the visibility of e-mail addresses, as most bots ignore CSS files.
In the past four months, that e-mail address has only received a single spam message in September, which was a typical SEO scam.
So it is interesting to see that they practically abandoned this type of e-mail harvesting. On the other hand, it could be that the harvesters are only after certain e-mail domains such as Gmail, Outlook, Yahoo, etc. addresses that are unlikely to be honey pots.
One method of e-mail harvesting that still seems to be ongoing is whois records. When I originally registered my domains, I did not expect my hosting provider to automatically use my account's e-mail address in the whois record and sure enough it started getting drug spam within a week.
