I'm watching TWIT from last night, and one of the topics they haven't got to yet but one I saw in the description was Yahoo to start reusing usernames. This was news to me so I googled it and found some articles from June and July. ..
If you got a "Used username" wouldn't this give them instant spam? Something about this doesn't seem like a good idea.
Remember the Yahoo! ID you had created to join chatrooms all those years ago? Well, kiss your email@example.com ID goodbye because Yahoo! is all set to recycle your old, unused ID in order to attract more users.
The mail service will be making IDs that have been lying dormant and unsed for over a year available to the public again, in an attempt to make the flailing mail service attractive to users yet again. In a blog post announcing this recycling project, Senior Vice President, Platforms for Yahoo!, Jay Rossiter writes that the mail service wants to give its loyal users as well as the new folks an opportunity to sign up for the ID they always wanted.
“If you’re like me, you want a Yahoo! ID that’s short, sweet, and memorable like firstname.lastname@example.org instead of email@example.com. A Yahoo! ID is not only your email address, it also gives you access to content tailored to your interests – like sports scores for your favorite teams, weather in your hometown, and news that matters to you,” wrote Rossiter.
Due to how easily it seems yahoo accounts are compromised I wouldn't touch yahoo mail with a
