Ignore them. If you're getting recruiters contacting you now, they'll contact you later. Don't worry about angering them with a no-reply. 1) They follow the money. If you can be placed, they'll forget that you blew then off 12 months ago; 2) The turn-over is extremely high for most agencies. Dustin Recruiter, who would be at home at a used car lot and can't even spell your name correctly, will be gone in a year. 3) Their emails are generally blast emails, sent to many recipients at once.
As far as the no-job stigma, that depends on the field. In software currently, recruiters/employers haven't batted a eye when they learn about a 2 month employment gap (most, in fact, are jealous of the time off).
