I have a commenter (not comment rater) that I programmed. It is 100% Macros. So it is slow (very slow) but also VERY human like. In the past months (August, September) the commenter was working perfectly fine. Every once in a while a comment would get flagged for spam. But now, my comments are instantly get marked as spam. And I KNOW for a fact that it is NOT because people are flagging my comments. I can literally comment, refresh the page, and it is already flagged. The system somehow just knows my comment is no good. I am pretty sure this is due to a recent algorithm change. About 90% of my comments get flagged for spam, instantly. The other 10% will stick for quite a while. It could possibly be the accounts maybe, as I have been using them for several weeks and they have not been banned or anything. It seems like it is youtube though. Anyone knows what causes this? What's it take to make an effective commenter bot?
