Tiny Social Signals Question

So I'm currently trying to rank my niches back to rank #1 on Google and Youtube, and was wondering a question that I've been thinking about recently but didn't think to ask it.

On AddMeFast, there is a "Twitter tweets" section, in which you can put your keywords into the tweet along with your video. Let's say I put up...500 of the SAME exact tweets. Is that not considered negative SEO? I mean, your video is in the same exact tweet across multiple users on Twitter, you'd think that would bring it down on Google.

nah man, that's only if you have the same anchor text spammed to death on different sites. But naturally tweets get re-tweeted with the same text, so it's fine. It's only going to help you.

No prob with this
It can come from website tweet button or retweet button
most of the time users dont change the text

a simple solution would be to create a tweet yourself and just use AMF for retweets. that way your tweet gets a viral feeling and the content of it will be considered important

No, they won't have any negative effect but will instead help you in improving your rankings.

No this is not duplicated content

Thanks guys, I'm not too great with trying to rank videos on Google and just needed that to be cleared up a bit. I appreciate all the input!
