Thank you for your advice. Perhaps I’ll flag after I get more SP :)

By the way, if it would be okay to you, I would like to translate this article into Japanese and post it in #Japanese tag. I’m a professional translator of Japanese, and on steemit I translate informative / inspiring english posts once a week, with the permission of the author. As our Japanese community is rather isolated due to the language barrier, also issue about spam comments is yet to be openly discussed there, introducing your post would be very helpful for our community. I’ll encourage readers to visit your page and upvote your post, of course. I’m glad if it would be acceptable for you!
