one of the drawbacks to allowing anyone to upload
anonymously to the system is that anyone can upload
anonymously to your system. :)

the best way to handle it is to establish a quota
for the ftp user, or even better, have it on its
own file system that won't bother any others.

the difficulty with removing the files and dirs is
that they are named with control characters and
such that you may not be able to see.

the quickest way to get rid of the files is to
run a shell with file-name completion as root. my
shell of choice is tcsh.  since it looks like
there are only spaces prepending, just do:

	rm -r /var/ftp/incoming/\ *

if you had icky control charaters there, you could
hit tab after the space which would expand out. also
don't forget to look for (dot) files... do a ls -la
to see everything

hope this helps.

-r
