Does youtube ipban comment spammers?

I'm new to this and I'm trying to make money out of spamming on youtube comments.

I spam PPC links (shorte.st) directing to a PPD (sharechash) and reply those links to random comments on youtube.

I'd like to know if I need to use a proxy server, (if youtube does ban and prevent spammers from making new accounts) Also, if you have any tips, I would like to hear them

Your need private proxies ....

When you spam your need to use the same proxie as you created the youtube account

Keep us updated good luck.

Buying youtube accounts might be better then spamming with proxies
