SO.ja allows "Post as a guest" and in some cases using the same email address, but it's recorded as a different account.

We need to repeatedly comment on how to merge accounts. Is this behavior correct?

Bug report on SO.ja meta


I understand how cookies work, but why ask guest users to enter their email address? If you don't use it to identify users, don't need an email address?

In some cases, accidentally created a second (or third!) account in less than 30 minutes.

    Doesn't posting as guest create a cookie-based account? As long as the cookie is around creating a real account will merge. But if the cookie got lost (different browser, different computer, security settings) a new cookie account is created. – rene Feb 5 at 8:03
  • When "posts as guests", email address required. Does entering an email address identify the guest user only by cookies? How do I use a "cookie-based account"? – cubick Feb 6 at 0:52
  • You use a cookie-based account by keeping the cookie alive. That is best done by always using the same browser and that browser shouldn't be too concerned about your privacy / cleaning up on closing a session. – rene Feb 6 at 7:04

    @rene Then why the email address is required to post as guests? Can't we alert if the address is already used when registering a new account? We, SOja users, spend a lot of time to let guests merge accounts. – nekketsuuu Feb 10 at 23:26
