What should I know before start my Youtube campaign?

I really don't use YouTube that much, and I've decided to try it. I have a lot of questions on YouTube.

I plan I posting many videos that will link to my website for my designated niche.

-Does YouTube ban accounts easily?
-Should proxies be used, and if so, are public proxies fine or will I have to use private proxies?
-Does YouTube flag accounts easily?
-Does commenting on different videos help at all in drawing traffic to your video?
Your personal experience that I should know about?

Thanks

-Does YouTube ban accounts easily?

Yes Youtube bans if you post porn or copyrighted videos. In reality it is a numbers game so better don't care abt it.

-Should proxies be used, and if so, are public proxies fine or will I have to use private proxies?
.
No public proxies won't work and your video or account will be instantly blocked. You have to use Private ones.

-Does YouTube flag accounts easily?

Flagging depends on your competitors. Once you reach at a level where your competitors might feel bad then they ll flag your video.

-Does commenting on different videos help at all in drawing traffic to your video?

Yes it helps but again if you post a comments like "See my videos" "watch my vidoes" you might get infractions to spam Youtube via comments.

Your personal experience that I should know about?

It is all about numbers game just do things at mass level then you could make money from Youtube. Also what I feel is your niche must be unique. If you use saturated niche it won't even convert 10K views to 1 lead lol..
