If you ignore a DMCA (Digital Millennium Copyright Act) notice (meaning you fail to remove copyrighted material or you ignore the notification), you could be sued in civil and criminal court. Penalties of up to $250K and five years in prison can be enforced. Even if jail time doesn’t result, your reputation will suffer. If you have violated copyright and find yourself in legal trouble, consult with an attorney. Then, consult with an online reputation management company to minimize long-term damage.
