Yahoo is taking a stand against people who employ ad blockers in their browsers by testing a feature that locks out Yahoo Mail users from accessing their accounts. The company says it’s testing the feature with a small set of U.S. users.

Users with an ad blocker installed in their browser who were included in Yahoo’s test were greeted with this message: “Uh oh…We are unable to display Yahoo Mail. Please disable Ad Blocker to continue using Yahoo Mail.” That message was shown to users on Chrome and Firefox browsers, according to a thread on Adblock Plus’ forum.

A Yahoo spokesperson offered this clarification to Engadget: “At Yahoo, we are continually developing and testing new product experiences. This is a test we’re running for a small number of Yahoo Mail users in the U.S.”

The Adblock Plus forum post that first reported the Yahoo Mail message pointed out that the URL includes the string “ADBLK_TRAP,” a not-so-subtle indication that the page acts as an unpleasant trap for unsuspecting users.

“Their users’ email account content are unique to them, so it’s different from news content where they can visit a competing website to get a same or similar experience,” said Tom Yeomans, CEO of anti-ad-blocker company Yavli, in an interview with Digiday.

Word of this test test with a “small number” of users has echoed throughout the Internet and is prompting some Yahoo Mail users to publicly declare their breakup with the email service.

PayPal vs. Venmo vs. Cash App vs. Apple Cash: which app should you use?

PayPal, Venmo, Cash App, and Apple Wallet apps on an iPhone.

We’re getting closer every day to an entirely cashless society. While some folks may still carry around a few bucks for emergencies, electronic payments are accepted nearly everywhere, and as mobile wallets expand, even traditional credit and debit cards are starting to fall by the wayside.

That means many of us are past the days of tossing a few bills onto the table to pay our share of a restaurant tab or slipping our pal a couple of bucks to help them out. Now, even those things are more easily doable from our smartphones than our physical wallets.

Online team collaboration is the new norm as companies spread their workforce across the globe. Gone are the days of primarily relying on group emails, as teams can now work together in real time using an instant chat-style interface, no matter where they are.

Using Microsoft Teams affords video conferencing, real-time discussions, document sharing and editing, and more for companies and corporations. It's one of many collaboration tools designed to bring company workers together in an online space. It’s not designed for communicating with family and friends, but for colleagues and clients.
