Hi, Nikolaos. It's certainly possible to do that with PCRE filtering, but I think it would block too many false positives from legitimate domains such as kissimmee.org, blackgirlsvote.com, savethedate.com, and cuteoverload.com (based on your examples). Maybe some other form(s) of content filtering? Steve Jenkins
