If anyone knows me by my username, this is the same username I've had on DeviantArt. Right now there is an evil user accusing me of having sex with dogs, casting spells on him, and bullying people to suicide. I was notified about his actions by an old friend and apparently people believe his lies and I don't know what to do. Clearly he plans to send an army of white knights after me. I'm at my wit's end right now and I don't know what to do. I can't afford a lawyer and I don't know if you can even sue someone over the internet without them having to fly to your location.
This has been going on for 4 months straight. What do I do?
People you know in real life really believe you are having sex with dogs, casting spells, and bullying people into suicide? Why would anyone believe that?
How are the people who know you reacting to you after reading these lies?
Do you know who is telling these lies? Do you know why these rather strange lies are being told about you in the first place?
You can have the stories about you personally reviewed by an attorney in your area who is well-versed in defamation law. If it appears you have a suit with merit, you can file suit in either your state or the state of the one who is posting the lies. Both states potentially could be found to have jurisdiction.
You need to keep in mind the statute of limitations for both states, which start from the date of first publication of the defamatory statements. These limitation periods may be different between your state and your defamer' state. You should file suit no later than the shorter of the times allowed.
I question how anyone could believe what was said but, if you have suffered severe reputational injury, the attorney you see can help you with your legal action. These are not inexpensive suits to pursue.
