On Saturday, Google temporarily disabled the ability to publish paid Chrome apps, extensions, and themes in the Chrome Web Store due to a surge in fraud.

"Earlier this month the Chrome Web Store team detected a significant increase in the number of fraudulent transactions involving paid Chrome extensions that aim to exploit users," said Simeon Vincent, developer advocate for Chrome Extensions, in a post to the Chromium Extensions forum. "Due to the scale of this abuse, we have temporarily disabled publishing paid items."
