YTtalk Mad
The thing I hated about the site were the people that gave you a thumbs up and a "good" without actually looking at your channel. This is a reason you should only try to promote one video at a time and give people a chance to look at it. The like and run discredits the site, though.I guess you were lucky then, because it always got feedback from the same people for some reason :/.
some people are saying its not worth it and some are saying it is and it's not a scam :'( confusing
