Im very interested in all the features, but I have one question. Is there a way to comment on all recently uploaded videos under a certain topic (with your main account to attract traffic).

I assume there is? Most importantly, however, is there a way to get your comments to stop being marked as spam, and not showing up under the videos. Or is there a certain limit to how many times one account can comment?

Basically, I would like to know if there is a way for me to comment on many videos from my main account without them being marked as spam.
