Blur lets you create temporary email addresses, phone numbers, and credit cards so you can avoid marketing spam and weirdos on Craigslist. Right now, you can grab a two-year subscription for $29 via TechnoBuffalo Deals.
Blur offers more than just disposable details. The temporary credit cards allow you to make purchases anywhere where cards are accepted, and you can choose to place a time or balance limit on each card. Likewise, you can set up a temporary phone number, and have calls and texts forwarded to your real number. This is particularly useful when you want to use a service once, but pass on the follow-up sales calls. Blur can also auto-fill your real credit card, billing address and personal info when needed, and it has a nice password manager. Free apps for iOS and Android mean you can create and delete details on the go, and everything is protected by AES-256 encryption.
