I am sorry to hear about this situation. You went at this the wrong way, so to speak. Instead of pursuing the attorney, someone in your situation should have pursued the party.
What should have been done from the very beginning is that once the other side refused to provide the FB account (or provided a redacted version), then someone in your situation could have filed a Motion to Compel production and let the Judge order them to do so.
At this point, the other side may have complied, or, filed a Motion for Protection asking the Court to allow the redaction, but they'd have to show a GOOD REASON as to why.
So what someone in your situation wants to do now is to simply file a Motion to Compel production of a non-redacted FB account. If they really did delete their account and it is no longer available, then someone in your situation can still possibly get it. This would be done by filing a subpoena to Facebook. Since FB keeps a deleted account "archived" for some time, they can likely provide a copy if subpoenaed (not the whole account, but some of it). Although FB is somewhat resistant to subpoenas and tries to shy away from them citing federal law, there are ways to force the issue (even if it means a compel order against the party itself to restore the account).
