I gathered it was for spam prevention.

I'd beg to differ.

In the following, I am using a T rather than a V for the well known drug:

I can see the word Tiagra is in the list, but I can easily tell that by 
swapping the i for a 1, it will be OK. Since that swap of i for 1 is 
common, other spam filters will pick up on it. But you are basically 
giving your rule set away.

I take your point that the list can be downloaded, but the average idiot 
finding that will not download the source code and check. They are far 
more likely to try a few combinations then give up. I think by making 
the list too public on your own site, the effectiveness is reduced.

I would say it is a bug if the software you use requires the file to be 
readable to the world. I would have thought it only necessary for a 
script to parse that file, not make it publically visable.

The default apache configuruation stops any files begginging .ht from 
being sent to a browser, yet they must have read permissions to the world.

Yes, I can understand you giving up with a guest book. I find it useful, 
as the one I run often gets comments from those in the railway industry, 
that I suspect might be relectant to post them if they had to register.

That works fine, if you don't have huge files. My uplink (download for 
you) is only 256 kbit/s, which would be far too small to host that 600MB 
5370B manual!!

I've got a few large files at http://www.g8wrb.org/ that really need 
professional hosting, but other sites I run, I host myself. (Old Sun 
SPARCstation 20).
