Linpha is indexed by default by search engine. An option is missing to avoid automatically undesired indexing, e.g. by goolge.
Add new configuration to avoid this
Add manually in header.php file the following lines:
<meta name="robots" content="noarchive">
<meta name="robots" content="noindex">
at the end of the </HEAD> section.
Add this automatically if configuration is set to not index.
Also a robot.txt file would be helpful to avoid indexing images.
