Arrgh Spam!

For the past several weeks, almost every day I get a notice of a comment on one particular past entry. Just that same entry. It's completely off topic. Some BOT keeps posting variations on an ad for buying brand name purses and wallets. Driving me nuts. I delete it every time and the bot puts up another one a day later.

Anyone else get this problem sometimes? Is there any better way to deal with it than just deleting every time it happens?
