In order to be sued for defamation, the independent contractor about whom you were writing would have to prove ALL of the following:
The elements for a cause of action for defamation are:
(1) A false and defamatory statement concerning the plaintiff
(2) An unprivileged communication to a third party
(3) Fault by the defendant amounting at least to negligence
(4) Special harm, damage to reputation, or the actionability of the statement irrespective of any special harm.
If what you wrote is true, the analysis would stop at #1 above. However, if the independent contractor makes a claim against you, then you will need a lawyer to defend your rights.
Defamation cases are very, very tricky and, because emotions run high.
But, remember, truth is an absolute defense in a defamation case.
Libel is publishing in print, which includes pictures, an untruth about another which will do harm to that person or his or her reputation, by tending to bring the target into ridicule, hatred, scorn or contempt of others.

It strikes me that it would cost this person quite a few hundred dollars to retain an attorney to undertake the type of investigation you are talking about. Subpoenas would need to be issued to the site to attempt to determine the source of the comment. If the posting is merely an opinion and not a recitation of false facts, there would, in all likelihood, be no cause of action against you for defamation. In the future, to avoid the kind of anxiety I am sure you are now experiencing, perhaps you should make your comments in person to the supervisor of this person, rather than falsifying an identity.
