Doubt about managing fake accounts

Hi guys, I would like to start managing, for example, fake youtube accounts to make comments on my videos or fake facebook accounts to like my fan pages. Imagining that I have 1k facebook accounts (purchased or automatically created), to use them I will also need 1000 private proxies? That will cost me $500 a month and will not be profitable being only a few (1000) fb accounts... So... I guess I'm thinking this in a wrong way. How many accounts can I use with the same proxy without being banned on facebook? Can I use free & public proxies to do this tasks? What's the best solution or the correct form to do this? How should I do and how much it will cost me?

I was thinking about coding a bot for facebook or just buying one, but first I need to know some things.

Thank you so much.
Regards.

How will you create 1k phone verified facebook pages? They will all keep on getting blocked and ask for phone verification, its too much hassle. Why don't you buy services of facebook likes or youtube comments? You can get good deal on this forum as well as on fiver as well. Also you can try using microworkers for this, you will atleast get likes from real people and not bots.

Hope this helps.

Thank you so much for your reply. I'm still looking for others recomendations. What happen if I have 300 youtube accounts to write fake comments? Do I still needing 300 proxies?

Regards.
