We are a New York Based company selling jewelry on-line. One of our disgruntled employee who was fired is conducting extensive slur campaign against us on the web. He has posted many complaints (posing as disgruntled customer) on consumer sites like ripoff report and scaminformer. All these are posted under fictitious names . He has further embarked on a systematic campaign on the web to malign our reputation through videos , blogs and twitter.
He also keeps sending e-mails to our current employees on their office e-mail ID urging them to move out from the company
This guy is clever enough to keep his slander campaign to our company only. None of his e-mails or slander has any physical violence or alike. He also used proxy server to hide his ip.
Would filing a suit remedy the situation?
What recourse do we have?
