I'm always perplexed at how annoyed the dev community gets at recruiters. Sure, it's weird when they don't put forth an effort, but come on, you're getting unsolicited job offers multiple times a week! We're EXTREMELY lucky that our industry is flourishing right now. So many people have been unemployed for months (years) and they can't so much as get a phone-call.

Take the recruitment as flattery. If you're not interested, delete it and move on. Better yet, forward it to someone who might be interested.
