XF 2.2 solved - Serve 410 error instead of 403 to bingbot

[Speil]

Hi,
I've got some sites of my forum on bing that should disappear there.
Permissions are already set to not viewable by guests / unregistered.

Problem now is, that Bingbot (Google is fine) is looking into the knwon URL and gets a 403 error. So it ignores my custom head tag:

<meta name="bingbot" content="noindex">

How can I force, e. g. show a 410 instead a 403 error to bingbot?

Got it, just using this code in htaccess

RewriteCond %{HTTP_USER_AGENT} (bingbot|^$)
RewriteRule ^ - [G]
