Yes and yes. SPAM -- why do you consider it to be a disturbing trend?

Every site I build for small business gets their email from visitors via very strict anti-spam filtering form mail and their email address is not revealed unless they choose to respond to the inquiry because it is a legitimate request.

As for Ad blockers -- I take it up a notch and block all javascript and manually allow whatever I know is the absolute minimum for the page to give me the info I need. The industry brought it on them selves plain and simple.
