Questions about ranking Youtube videos

I wanted to try and rank a few videos on youtube.
I was going to create 2-3 similar videos on different accounts, and try different techniques to try and rank them.
If they fail, oh well.
My concern is, since Youtube is owned by Google, should I be a little more careful, since they'd pretty much know all three accounts are the same person?
And also if I have my link in the description for my site, does anyone think if I use blackhat on the video and my site is in the description Google may notice that? Not necessarily penalize but connect the youtube account to my site and have it on file that they are connected?

If you upload similar video with different accounts and IPs then I don't think so there will be some problem at least until they rank. Try to add some different layers or slides before and end of the video to avoid video vanishing. Same description with same website link doesn't matter for Google. Google never connect or make long distances between links short.

YouTube removes duplicate videos. Especially if they're connected/on the same account. So you have to add 0.5 seconds to the beginning and end of each video and mix them up so YT doesn't know they're duplicates.

You need backlinks to rank a Youtube video at Google. A Youtube video can't be deindexed by Google except the video violates the rules.
