Best proxies for yootoob advertiser?

I use 20 accounts and no multithreading. I am currently using free proxies scraped from everywhere. The free proxies usually die very quickly and this causes problems with YTA.

I don't wanna invest too much on proxies. So, anywhere I can get free or really cheap reliable proxies that don't die quickly?

i use to provide proxies for a guy on here that posted cpa offers on utube
via a bot - is that the same thing ?
