Best Proxies For Pinterest(?)

I had my summer holiday and now getting back to getting some pocket change, i'm going to launch a website in a few days, maybe today.
Traffic would be arriving from social media, pinterest for start so i need to know which is currently most cost effective proxy supplier.

I have around 200 accounts but dunno if i'm going to use all of them in beginning so good package of 10-30 private proxies would be ideal (2acc/1prox).

Last time i think i used buyproxies.org but dont know if they are still good choise (used their shared proxies but they got saturated after pinterest marketing got more known, ghosted proxies) but their private ones looks kinda steep (after money starts rolling again i will buy steep ones, cheaps go long way in the beginning)

Looking at squidproxies atm, but before i do anything i need hints from you guys.

i have used 200 proxies with 1000 pinterest account and no problems !

spy, I'm assuming they are all private proxies? Cuz it would seem that publics are probably going to fail 90% of the time.

I've been good with a few private ips, but the commenting with pinpioneer has not been working today, not sure what is up.
