Hi, I am using YouTube to mass comment on a lot of videos. It started off great. My comments stuck until they started to get marked as spam, which is fine, at least I know what has happened to them. A couple weeks on from here, my comments don't last more than an hour, they all seem to get removed, but not by video owners and they are not marked as spam, they just disappear, yet the weird thing is, I see other people spamming on every videos, and their comments stick, what is happening to my comments and what should I do? Please help, thanks.
