Short version: I was asked by someone I hardly knew to put them in touch with someone in my professional network. I gave them a name, but I now feel uncomfortable with it. For the next time:
How to politely refuse to put someone in touch with my professional network?
Background
I am a young academic, teaching in executive education (i.e. to people older than me). Through my personal network, my studies, and previous professional experience, I have professional contacts in the industry. These contacts are public (on LinkedIn).
The other day, I was informally talking with a student (who has 10y+ work experience) during a university's reception. This student wanted to transition from one field to another (in which I have multiple contacts).
He asked me if I knew someone in his new field (I used to work in) and if I could put him in touch with them.
Problem
I genuinely answered that I know people in the field he wants to transition to (answering no would have been awkward as I happened to worked in this field), and ended up giving him the name of a friend/contact in this field. (I didn't play the go-between, just gave him a name — without making explicit whether he could say "{ebosi} said I could contact you (on their behalf)" or just "{ebosi} told me about you".
However, I don't feel comfortable, as I didn't know this student at all (the reception was for all master's student and he's in a class I don't teach to). I felt like I somehow put my reputation into play for someone I'm not sure I want to.
Moreover, I'm not sure about his intentions (just asking for a candid 20mins talk to better know the field, or aggressively asking for work) — I know it's my fault for not having check that beforehand, though.
The fact he send me an email after 36h saying "your contact hasn't answered me" make me fear he might be toxic… and thus harm my relationship with this industry contact.
Question
To avoid this unpleasantness in the future, I am wondering
How to politely refuse to put someone in touch with my professional network?
I am not comfortable with the idea of saying "I don't know anyone in this field" when it's an blatant lie.
For having answers useful to a larger amount of people, please consider cases where you don't want to put the person in touch because:
- you don't really know the person who is asking (e.g., you've just met them at a cocktail party),
- you already know the person who is asking (e.g. a coworker, student, personal friend) and have motives (legitimate or not) for not wanting to put them in contact with your professional network (e.g., toxic person, would make you look bad, don't want to bother your contacts, …).
