Use example.com as the domain for sample URLs:


to mark them as sample text instead of a 'live' URL (which yours is not). mysite.com is an actual domain, and you should not use it even in sample URLs. The domain is explicitly blocked on Stack Overflow.

example.com (or the .org, .net or .edu variants) on the other hand, is specifically reserved (by RFC 2606) for this very purpose.

  • But oddly I can ask a question with it in (see above).

  • The site name is not blocked here as that would make it needlessly hard to ask questions about the block. Commented Mar 20, 2014 at 8:57
