on a side note, http://l2.io/ip.js is pretty cool. since it allows script injection into the return, it can be used clientside to inject their ip into the webpage. Pretty cool if you're posting from static html to a 3rd party form.
mailbait is not intended to signup for spam.
The email returned is solicited from legitimate services; including listservs, newsletters, and anything else users dig up to add to the system.
This makes it a good fit for some tests, as inbound email is not necessarily from illegitimate sources with negative intentions.
You've just taken this to a whole new level. Should mailbait be extended to pair name/address with forms online? I could modify my woodburning stove and heat my house... think how much energy i'd be saving and not have to draw from a coal-fired powerplant!
faster is only one aspect of a scalable solution. perhaps thought has been given to the potential for abuse, and trying to keep from trashing the servers on the other side.
Sure, TCP carries the requests, but i think k2h was referring to the javascript running clientside. tear apart the .js on the site. mailbait servers don't fill out any forms. client browsers do.
