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 baed my IG accounts get baed too.

Thanks for your help.
