I received a job offer that I needed to reject because I feel it would not be the right fit. However, the (3rd party) recruiter seems to not want to take no for an answer and is accusing me of being dishonorable. I did verbally accept, but called later to retract and did not sign anything. I also spoke to the company HR and hiring manager directly about my intent to not go forward, and we seem to have parted on good terms.
Can the recruiter do anything to me? He seems to suggest he'll damage my reputation in the industry, naming people that I've worked for before that I know and respect.
