A lawyer representing more than a dozen celebrities whose personal and sometimes nude photos were stolen and shared on the Internet issued a scathing letter to Google that accuses the tech giant of helping the images spread and threatens a $100 million lawsuit. The letter, written by lawyer Marty Singer and obtained by The Hollywood Reporter, calls Google’s conduct “despicable” for what it says is Google’s failure to remove the images and its “facilitating and perpetuating the unlawful conduct.” Google did not immediately respond to TIME’s request for comment, though the firm has removed some images from its sites and links to the images from its search engine.
