Same proxy for Instagram and Facebook?

Is it Possible to run 3 Instagram Accounts and 3 Facebook Accounts on the same proxy? Mine are IG Proxies from sslprivatexroxy.

I wouldn't even think twice to combine IG and twitter on one proxy but since IG belongs to FB i am not sure that if a FB account gets banned my IG accounts get banned too.

Thanks for your help.

They are completely separate companies, so I assume they don't do any cross checking of any sorts. I also wouldn't use 3 ig accounts on one proxy... Personal preference I guess
