Malformed newsgroup control messages

Hi,

We are seeing frequent control messages to non-existing french newsgroups
on our news server.Noticed newsgoups have some french (special) character
and from badcontrol.log is reported as "Malformed newsgroup name".

Everytime we get few of these malformed newsgroups postings have noticed
Load avg. on news servers shoots up momentarily. What would be the best
method to block/restrict these control message postings ?

Could I just just use control.ctl to drop any control messages for newsgroup
in question alt.fr.letters.*. Will this help with the issue we are noticing ?


 From badcontrol.log:
