1) Set up an independent "throw-away" email address
2) Sign up for google voice and get a "throw-away" phone number
3) Set the number to "do not disturb"
4) Post on gaswork and doccafe and only give out the throw-away number and email
5) Screen all the replies and offers and have built in responses to the masses of recruiters
6) Over time you weed out the spammers and learn who is actually trying to find you a spot versus who got your number off some master list and is merely adding you to their email blasts every other day
7) Work and talk on the phone exclusively with the "good" recruiters and ignore the others
