Dozens of search terms like those below have appeared on our 18.104.22.168 installation since the very beginning and they're quite heavily used (over 800 times each). I'm just wondering if any of you has experienced the same thing? ... or is it a security attack on our website or a new Google crawl pattern? We deleted them all from Catalog > Search Terms > Select All > Delete but they all came back again today...
Never experienced such thing on any other Magento installation. Please advise and thank you all for your help ;-)
