Which VPN to use with Instagram?

I have free proxies for a bot software already but I'll need a way to edit bios and check inboxes so I'm thinking about using a vpn to save money rather than buying lots of proxies to manage my accounts. Which VPN has clean IP's or what should I do? Bite the bullet and pay for proxies?

If you're thinking about buying those commercial VPN solutions like HMA, StrongVPN, TunnelBear etc., those won't be good for this purpose, because those are not unique ips, but shared ones, hence the low price for that many locations.

You should go with dedicated private proxies. Dedicated VPNs are 3-4 times the price of dedicated private proxies.
