So why don't you keep testing, seriously look how weak you sound no offense but your complaining about 1 single top comment not being on the top anymore and you expect to get the answer handed to you in a silver platter, plus not even considering how profitable comment rating is, and yet you think people are going to help and pm you tricks lol. Dude people that do comment rating, they aren't the friendly or the most open people you will meet these people take this shit seriously they don't fuck around hence why you don't see any real tuts on comment rating.
What you have done there is basically ask for help without really doing any work, thats where 90% of the game is with comment rating, 10% your bot 90% research and finding out how to get past the filter. Now your even saying you do your comments manually, lol thats another like big LOL. So whats benefit would a person that knows how to comment and rate would get by teaching a noob where the noob doesn't even have any bots or anything to gain, i mean seriously shit doesn't just fall from the sky. If you seriously want to figure out whats wrong with your shit, you should first atleast attempt at testing it for your own. That problem you have is one that many noobs have , in fact is probably the most common in comment rating. So your not the only one with the problem, but people who have figured it out certainly didn't spend time writing forum posts on bhw or another forum.
Point is, look what happened to craigslist section here on bhw. IT became on privatised on the jr vip section and the talk about how to post on craigslist diminish from the open eyes, because it was super profitable. Same thing is for youtube comment rating, is the most profitable shit you can do on youtube and very few people want to keep it like that for them. If this hasn't made sense to you ask yourself, what happened to all the comment raters besides those shitty ass browser ubot piece of shit, mmmm.... strange right no really free public bots. So why would people share free public info about comment rating on one of the most profitable niches without getting anything back.
I still don't know why people still keep posting this shit, i mean i could probably go on and on and try to educate people on comment rating but its no use, people just want to get shit for free without doing the work of testing and researching. There is a reason why pepsi and coke spends billions on R&D(research and development).
I can tell you i found my tricks and info from comment rating from actually performing tests, not asking ppl on forums and asking for answers by pm.
