I understand the need to flag spam, and I think you're doing a great service by helping to downvote haejin's posts to a reasonable payout level. However, not all one word comments are spam, some if not many are legit replies of approval on other comments. It doesn't matter much as far as payout goes, as even legit one word comments probably don't deserve upvotes, but it does affect reputation negatively, and is also a bit of a waste of your own resources.
As a teacher of ESL on Steem, I WELCOME one word comments if they are relevant and/or show engagement with the learning material I've posted. Please take this into consideration should you decide to fine-tune the code in your voting bot. I would hate to see one of my followers downvoted for trying to use the English they've learned by commenting.
Other than that, I fully support what you're doing. Thank you for your contribution to Steem.
He's also using it to down vote any genuine content providers/posters who he just doesn't like... Like myself. Abuse of the system for his personal agenda. And he's why I, and others, are powering down and leaving. Nothing but a bully.
There is absolutely NO single word that provides anything useful to ANY conversation, in my opinion. It's nothing but useless blockchain drivel.
