Recruiters can be annoying, but they're also just doing their jobs. I think it would be better if you collected some templates for politely copy & paste point out why you're not interested on the website. If people don't back off, you can still send something that's worded more strongly.
The recruiters that annoy me are the ones who blatantly send me copy and pasted messages while clearly just having done a keyword search (and certainly not reading the parts about what I’m not interested in), who go quiet as soon as I ask for specific information (or make it clear that I expect a sufficiently large benefits package over what I have to make it worth my while), who don’t pay attention to my location but require me to work on site. Basically the ones who are wasting my time and are rude to me. Those people can go f themselves.
I have had a few, rare, great interactions with recruiters who seemed to genuinely care about placing good candidates in good companies in positions that the candidate is well suited to. Unfortunately for every one of those I’ve interacted with, I get 50 messages from the ”hey I have a lowish paying role doing something you specifically said you didn’t want to do” recruiters.
Agreed. While I'm a fan of being terse when justified, these folks aren't telemarketers peddling medical back braces or whatever. They're trying to do right by many others. And while we might be gainfully employed now, burning a bridge isn't necessary nor wise.
