I am not sure that you can link to an individual comment, but you can link to the community mod log or the user mod log depending on the circumstance. Or you can link to the individual comment in the thread, even if it has been removed.
It is preferred to reach out to a moderator(s) by direct message, in which case you could include a screen image of the mod log along with your question.
I understand why one may have an interest in asking questions publicly, although it makes is very difficult for mods to respond (unless you tag us). If you are interesting in getting a response, this is perhaps the least efficient way. We are assured to see report, and likely to see a DM in a much more reasonable time.
