Not really a domain issue, but there seems to be a greater than average knowledge of coding on this forum so thought it may be a good place to ask. We're recently launched a new site and found that someone is masking or mapping their domain onto our site. It's not scrapped as any edits appear immediately. Looking at the source code there is also no iframe present (hence assuming they're mapping or masking). And ideas on how to stop them? Ideally just refuse the connection so nothing outputs?
