The HN guidelines and FAQ make it clear that it's not OK to ask people to upvote or comment on your stuff:

And the HN community is very quick to notice it, flag the post and comments, and email us, all of which happened here.

There's no need to try and game HN like this. We're always looking for interesting new projects to showcase via Show HN, and we routinely spend substantial amounts of time helping people polish their Show HN posts, and if we think the community may find it interesting, we'll put it in the second chance pool (https://news.ycombinator.com/pool, explained here https://news.ycombinator.com/item?id=26998308), which guarantees it a bit of front page time, without the bad vibes and negative sentiment you attract from trying to game HN.
