I'm getting a crazy amount of spam traffic through supersearch. They are all for 13-digit ISBNs (book UPCs). Since we are an online bookstore, I didn't notice it at first, but we're getting about 1000 searches per hour(!) for products obviously unrelated to our website (we sell construction books).
Is there a way I can filter or block this spam? For that matter, is there a way I can find the IP address where these searches are coming from (assuming the IP address is static)?
