At this point in my career I start all head-hunter conversations with "I work 100% remote as a W2 employee (not contractor) with full benefits. I travel 1 - 2 weeks a year, work 40 hours a week, and make $x. If you can meet or beat that let's keep talking, otherwise thanks for your time."
It keeps the conversation short which is nice for both me and the recruiter. And if they have something interesting to say then I know it's worth my time.
I remember sending ICQ messages to friends while sitting in traffic on I-635. It was kinda unbelievable to be online in a car
