Q:[/B] Why do I need such a thing?
A: To screw spambots.
Q: Does this do anything about human spammers?
A: No, this works only on automated login attempts - but the actual human spammer has become more and more rare and is easily dealt with in other ways - most of them which do exist, still use automated programs to login anyway.
Q: Has this been tested at all?
A: Yes, extensively. The [OzzModz] Login Spaminator has logged over 10 thousand blocked bot login attempts in exhaustive testing for five months on several forums - without allowing ANY successful automated logins or ever interfering with any legitimate human.
Q: Does this alert any possible real people that their login has been rejected?
A: No, there are no "gotchas" in the Spaminator, because no legitimate humans will ever see it or even know it is there. Xrumer and other automated spam systems are programmed to flag sites that present warnings, "gotchas" or alerts, even unusual behavior like loading an unexpected page - allowing the human system operator to investigate why logins are being rejected. This information is passed on to the program developers and improvements are added to defeat the blocks. It's why most every anti-spam measure eventually gets defeated. They rat themselves out! Spaminator does not. Additionally, the rare human spammer mostly still uses automation to get logged in. Why tell them what they're up against?
Q: What about if this becomes widely used, won't the spam system programmers easily defeat it like everything else?
A: We shall see, they'll definitely try. But we've not only thought of that, we've planned for it in advance. Many other features for this are being developed and tested, and some are ready for deployment as the need arises. We don't go into battle with just one or two weapons or ideas.
