The only way we keep track of users of our free products is with an anonymous userID. If your extension has not been upgraded to Premium, you will see our optional payment page when we release updates to the extension.

If your extension has not been upgraded to Premium, when we update the extension we'll display the payment page to let you know about any new Premium features and offer you the option to upgrade. Feel free to close the page by clicking the "x" on the tab. We are also frustrated by Twitch's ability to circumvent our blocks. We hope to have these blocked again but it may take some time to block them all fully. — Kat C., AdBlock Support
