Naive on my part but I've always used my a business email address associated to my domain registrations. EG domains AT businessname Dot com
About 3 months ago I started getting hammered by spam. I eventually got jack of it and couldn't block it, so I lodged a complaint. Seems the sender got given my details. A few days later I noticed a huge spike in traffic. And it's coming from what looks to be a redirected p#rn site.
What concerns me is not only the traffic but also the link juice being pushed to my business from this dodgy site.
Is there a way in htaccess I can redirect the bad domain pointing to my business site, to some place else, a bogus URL for instance.
You can't redirect another site away from your domain without accessing that other site and altering the server configuration of that site.
You can, however, redirect visitors that come to your site via the redirect and redirect them somewhere else or block their access.
You can't affect how searchengines crawl this redirect. They do not come "via" the other site and do not provide a referrer. They access the other site and make a note where it redirects to, and then much later on they directly access your site.
