Sure, I see it all day.

What they're trying to achieve is determine whether you have an "open" FTP 
server which allows them to store "warez" and download them again.

A simple countermeasure against this is to give files that are uploaded to your 
"incoming" directory permissions so that anonymous users can't access them 
anymore. You can even prohibit them from reading the directory's contents so 
that they don't even see which files are stored inside the directory.
