Pinterest Private Proxies?

hey.
does anyone know where i can get private proxies that work well on pinterest?
i will be manually logging into my pinterest accounts and performing actions with these proxies, so i won't really be using software.
the private proxies that i have now are not working.
for example, i click "follow" to follow someone but my account "following" section does not go up, it just stays the same.
then i tried this from my home ip and everything was fine, so the proxies are definitely the problem.
i will appreciate any help.
thank you.

up!
Has anyone a recommendation on what you should take care of when buying a private proxy for Pinterest?
(port, country, etc.)

SharedProxies.com have been working fine for me as far as auto account creation (this is provided by a third party so I can't comment on the method but it's using proxies that I supply) and manual logins and performing actions.

I have been having issues using Pinterest bots through SharedProxies though - nigh on unuseable ATM.
