multiple youtube accounts need ip?

i bought 25 yt accounts here on bhw, my plan is to use them to upload niche vids for local businesses in diffrent u.s locations, many of the accounts will have the same video on it. i do this all from my laptop. does youtube see that all these accounts are from my one ip? (also google chrome is my browser) and if so would it effect my ranking top page for local searching? recently i uploaded and did seo for a vid in several small towns with under 100 searches a month and...nothing not even top 50 pages. any help with y this is happening?

Of course it does, and from the sound of it, you are not deleting your flash cookies either...

Always ask if you get the IPs along with the accounts before you make a purchase. I'm guessing you probably have to phone verify them again if YT detects unusual IP logins from a different country.

thanks had no idea about the flash cookies, just looked that up... another question would changing or switching my ip with like platinum hider work? (u.s.a based proxies?) or is that 2 risky?
