Personally, I make the most of it. I try to see how far I can push the recruiters while still having them respond to me. Here's one such exchange. (I went all-caps because for some reason he emailed me in all-caps. He went back to normal but I decided to stick with it.)

Recruiter:

------------

Hey Aerovistae, THIS IS A GREAT POSITION FOR YOU IF YOU WANT TO GET IN THE FIELD OF SOFTWARE DEVELOPMENT. take a look please!

I am a technical recruiter and have a great job opening in Waltham that I was wondering if you would be interested in! Ive included some details on the position below, drop me a line if you have any interest! Thanks

Me:

I WOULD LOVE TO GET INTO THE FIELD OF SOFTWARE DEVELOPMENT

Recruiter:

Hey Aerovistae, Would you like to speak over the phone this evening sometime? -Eric

--------- Me:

I DO NOT HAVE A PHONE

--------- Recruiter:

Hey Aerovistae, My phone recently broke also, so I feel your pain, but will you have access to a phone in the near future?

---------

I HAVE RECENTLY ARRIVED IN SRI LANKA AND THE BROADBAND INTERNET HERE IS VERY GOOD BUT THE PHONE IS VERY EXPENSIVE, CAN YOU ACCEPT COLLECT CALLS?

After that he finally stopped responding. I have a whole folder of these. I think my favorite one is the time I tried to get the recruiter to do a CAPTCHA to prove he was a real person and not an automated bot.
