Luminati might be a good choice or cheapest and unlimited way is to build your own proxy service with 4G dongles, so after restart you have new ip and so on.
I'm kinda shocked those aren't blacklisted and the accounts auto banned. You don't use a private proxy?You can try your luck with proxysite.com/facebook or ProxFree. These are the ones I use almost all the time. -Micah
There is no difference what 4g service use. It is important that u use residental ip addresses for proxy. Datacenter IP's are not goodLumanati seems expensive as hell. Also what dongles and 4g service do you reccomend?
