We should ruthlessly close questions which are inappropriate for us, though I have a plot twist:
A few weeks ago I had a discussion with one of the Webmasters moderators, who expressed interest in having questions like this migrated there. They are especially interested in receiving questions about shared web hosting, control panels like cPanel and Plesk, and basic Apache .htaccess stuff.
In future, if you see such a question and it isn't completely brainless, consider flagging it for migration to Webmasters.
As for the tags, I don't believe they should be burninated, but they should have warnings added to their excerpts (the most likely thing someone will see before asking their question) that their question may be better asked on another site.
