Some months ago on NL.linux.org I used to have trouble with
this too.

The solution was to rate-limit /incoming to 3kB/second and
put a README.WAREZ file there warning them of the fact that
the directory is rate-limited and completely unsuitable for
bulk transfers.

They haven't bothered since ;)

[well, the first evening I had some fun watching a kiddie
upload a file at 90kB/second, after which his friends couldn't
download it before growing old ... but after that they were gone]

regards,

Rik
