What are the grounds to press charges for slander or defamation of character?
If a person posts slanderous remarks about you online, but doesn't say your name yet gives all of the relevant clues, can I pursue action?
Possibly. It depends on two different elements:
1) How specifically are you identified, based on the "relevant clues" and context? If you can show that the person named or described can only be you, you may be able to establish a case.
2) Remember, that defamation is a false statement of fact casts a person in a negative light and causes them some injury or damage, including reputational damage. Opinions, no matter how negative, are not defamaton and nor are statements that can be proven to be true. Only false facts give rise to defamation.
If given the above, you believe you have been defamed, you should consult with an attorney with defamaton experience (particularly involving the internet), with whom you can share all the facts a nd details of the situation.
