I assumed that anyone who actually cared to reproduce the problem
would just run the script, because that's all I did.

Running the script out of the box with the default settings
will reproduce the problem within a few hours of scanning. You will
get tons of corrupted Torpark exes in your docs dir. Seems to really
like Torpark more than anything else. Probably cause its the biggest.

Here is the error:

  <title>503 - Connect failed (Privoxy at localhost.localdomain)</title>
          This is <a href="http://www.privoxy.org/">Privoxy</a> 3.0.3
on localhost.localdomain (127.0.0.1), port 8118<!-- @if-can-toggle-start -->,

It's embedded in the exe. strings won't find it, but grep will.

Client is wget. Apparently it does retry after failure. Manpage says
nothing about status codes. Maybe it doesn't know what to do with 503.

Yeah, I'm thinking the connection most likely broke down, wget retried
and tried to continue the stream, but Privoxy came back with its 503
status error page instead, probably not something wget was looking
for. Wget probably tried once more after that connection closed, and
picked up the stream again.

Unfortunately my copy of curl is ignoring HTTP proxy environment
variables and --proxy command line settings, so I can't check to see
if it has the same property.
