We have 100s of bots for posts but if someone initiate a project exclusively for comments only then it will have tremendous demands and let me tell you if you have decent SP like 2000 or so and if you dedicate this bot for comments only in stead of posts then it will be the best ever project in steemit in recent time.
If you dont have SP then take some lease from open market and make this project bigger.
Thank you.
thank for your advice! Maybe we will try to change our rules when we have more users. I'll keep your words in mind, and thanks again for the idea!
