Human assisted registration is becoming more popular - apparently there is even
setups where they auto farm-out the capcha recognition to pools of people who
simply enter the stuff and the system processes everything else automatically.
On forums, even with capcha, there is an element that persists. The best
solutions have been to ban the most frequent abused mail systems, and
potentially block problem IP ranges (like Asia). How much you can do that
depends on your list's scope.
In short - yes there appear to be human assisted automated spam generation
systems in play. Systems with a confirm email have also been mass defeated
with software, but most hacks don't bother to build their own and try to use
pre-made spamming software. Unless mailman has been targeted by these
developers in the past, its unlikely someone is using pure software to automate
it.
