NOTE: you mailed this to the curl-main mailing list and to the admin address
of the libcurl list. There's no point in mailing the admin address with
normal list posts.

Well, we can't actually know anything since we don't know anything about your
script, your bandwidth, the site you're talking about and its bandwidth.

Many site owners considers it a bad thing to "suck" every web page from
his/hers site, especially if done with a very high speed (no pause between
the fetches). Also, if the remote site has a limited bandwidth while you have
much better, there's indeed the possibility that you starve out other
visitors from the site while you're downloading the (entire) site.

If the server was messed up by your script, then it surely must be a silly
server, but then there are no laws against that and many a server out there
are truly stupid.

You might get more popular if you make sure your script doesn't work quite as
fast as it can. Most search engines, for example, only make one request a
second during harvesting.
