question on comment views - can they be removed without mod notification?

hi dear reddit volunteers

** as stated, my question is - can the owner and mod of a sub remove or make invisible comments without notifying the commenter?**

thank you! hopefully this question wasnt too dumb

((context if needed: im in a local sub run by exactly one person.
a recent comment of mine has not gotten removed, and i noticed that my comment went back to being seen by 0 users, when a few minutes ago it showed 9))
