@rainchen pretty much yes. The point with steembots is to encourage responsible bot ownership like you would encourage responsible pet ownership. Things like spamming would be bad. However having a bot that can monitor in real time the conversations that are going on, and then quickly posting some info with a link to your blog would be undetectable from human activity.
It's not a simple task, but it can be done. Trick is not to piss everyone off by spamming the same things over and over again and making sure the bot only responds when there is a good deal of relevance.
Im strongly support on this bot. Hopefully they will be launch asap :D
