--- Comment #4 from Frédéric Buclin <LpSolit at netscape dot net> --- (In reply to Manuel López-Ibáñez from comment #3) > I wonder about the effort required to do such a thing. Some of those emails > seem fake, is there some kind of confirmation email for newly created > accounts? Yes. When a user requests a new account, an email is sent to that email address, and the user must click on the link which is in the email to confirm that 1) the email address is valid, and 2) it belongs to the user who wants to create the bugzilla account. Clicking on this link will display a page where the user must type his new password, and only after that is the bugzilla account activated. It is not possible to create bugzilla accounts automatically using the API (to prevent such problems). > Limiting the number of bug reports per new account seems a good measure, but > also easily circumvented as long as someone can create as many new users as > they wish and each user stays below the limit. I agree, that's a problem. But I think there isn't one single solution which fixes all cases, but rather multiple solutions which, when combined together, can give a reasonable level of spam prevention.
