Hate the dirty recruitment tactics

I hate it when recruiters reach out to you with a message indicating that they are looking for 'key positions' and when you follow up, the tone changes to "we're just looking for engineers." This happens all the time and the latest company to play this recruitment tactic is LinkedIn. Guys, can't you decide whether you are looking to fill a 'key position' or just an engineering position before reaching out to candidates? I can see that mentioning 'key position' will get a candidate's attention but this is just a low level tactic.
