Re: [feature] anti Spambot solutions

Your point is valid.

Do the harvesters actually execute javascript?  I
cannot imagine that they do.  Their methods are based
on collecting the maximum number of addresses in the
shortest period of time, executing javascript and
having it output a real address would consume too much
time I would surmise.  I could be wrong.

Perhaps someone could clear this all up with a couple
of examples of harvesters that can execute JS and
output and address.
