Fortunately I'm not the kind of person people would be searching for, but this just seems impolite. Posting to an internet forum on a topic that interests you is not an opt-in to have random internet people or reach out to you asking for free advice. If I were a domain expert I wouldn't want to be searched for on Reddit using a tool like this because the implicit goal is to then be spammed about it. If I wanted to be reached out to, I'd say so on a web site somewhere
