Recruiter: I found your email on LinkedIn and I have a few Java positions you might be interested in. Would you be interested in
Me: I don't have a LinkedIn account. How did you actually find my info?
Recruiter: It was in a database we share with a few other recruitment agencies.
Me: Could you remove me from the database?
Recruiter: Okay, you have been removed from the database.
Me: Since we both know you didn't delete it, you at least update it to say I'm interested in Python jobs? I haven't worked in Java in 5 years and have no interest in going back.
Recruiter: Okay, I've added Python to your languages.
Me: But you didn't remove me from the database and you didn't remove Java from my languages?
Recruiter: I'm not authorized to remove data from the database.
Me: So you lied about where you got my info and you lied about deleting my data from your database?
I like to think that after this he had a revelation and switched careers, but more likely he moved on to prey on another sucker.
EDIT: This was from a new recruitment address. Most recruitment emails I receive get filtered and receive an automated response telling them politely that I'm not interested in their services.
