Facebook + Proxies: Question!

Hey guys.

So I buy facebook accs with cookies and then I post my t shirts in Facebook groups in my home country. It's going great and I am making good money. However I need to ask, which proxy provider is best to do this with? Because my accounts are getting destroyed now. I used VPN services like SetupVPN etc and I had the feeling they worked fine at first, but now, 1 month later, my accounts dies instantaneously! So I guess I am missing something crucial! I just want to manually enter the ip etc into a proxy switcher and then go manually into my accounts through a cookie editor and do it all manually. However, to my understanding I need Elite Proxies? So... What Proxy Service would you recommend in my situation? I will only use Facebook with the IPs and fresh bought PVA's with Cookies. 1-3 accs per IP! Thanks!

Using a VPN in this case it's the worst choice you can make. Use some residential proxies or, better, some 4G/LTE ones

Firstly facebook can track not only what proxies You are using.
Check this site and see only part of things what is easy to track. http://whoer.net/ext
It is possible to track plugins, fonts and many other things what is static on Your PC.
So facebook can track You down that all for example 100 accounts are used from same PC and does similar actions.

If thats the case then there is no easy solution, but to make sure thats the case I would suggest to picks 1-3 accounts and use them without proxies and see what happens, if they gets banned then obvious its not proxy fault.

In short facebook is much more complex then it was before all those Cambridge analytics and other data breach scandals...
