Sadly, it's often a good idea to preface "Show HN" submissions with this nowadays so that someone else doesn't tell you how useless your project is in the comments thread.
Sort of, except that this is usually considered as down vote baiting on HN and is frowned upon. From HN's guidelines: "Please don't bait other users by inviting them to downmod you."[0]. In this case though, I don't feel it was OP's intention to invite down votes.
