download - wget decides not to load because of black list

I'm trying to make a full copy of a web site; e.g.,

http://vfilesarchive.bgmod.com/files/

I'm running

wget -r -level=inf -R "index.html*" --debug http://vfilesarchive.bgmod.com/files/

and getting, for example

Deciding whether to enqueue "http://vfilesarchive.bgmod.com/files/Half-Life%D0%92%D0%86/".
Already on the black list.
Decided NOT to load it.

What is happening?  What does wget mean by "black list", why is it downloading only parts of what is there, and what should I do to get the entire web site?

The version of wget is

GNU Wget 1.20 built on mingw32

(running on Windows 10 x64).

P.S. I think I've managed to solve this with

wget -m --restrict-file-names=nocontrol --no-iri -R "index.html*" 

even though the filenames are slightly crippled due to special chars in URLs.  Is there a better solution?
