Gah..! visitor message spam.. How to deal with it..?

[محروم.كوم]

I have a spammer doing a lot of visitor message spam (Russian 'dating' spam..)

I can delete the user and their posts but that doesn't seem to delete all their visitor messages..

Any tips or how to cope with this please?

If a spammer is reported how can I erase all the spam visitor messages they have left?


Thanks in advance.. __DEFINE_LIKE_SHARE__
