if you need to block a ip-number, iptable rules may be useful:
iptable -A INPUT -s x.y.z.w -d 0/0 -j DROP
PHP method to redirect the user back to the page, add this in the top:
if ($_SERVER['HTTP_REFERER']=="the referer page") {
header("Location: {$_SERVER['HTTP_REFERER']}");
}
Apache rules (not tested), we redirect them back:
RewriteMap deflector txt:/path/to/deflector.map
RewriteCond %{HTTP_REFERER} !=""
RewriteCond ${deflector:%{HTTP_REFERER}} ^-$
RewriteRule ^.* %{HTTP_REFERER} [R,L]
RewriteCond %{HTTP_REFERER} !=""
RewriteCond ${deflector:%{HTTP_REFERER}|NOT-FOUND} !=NOT-FOUND
RewriteRule ^.* ${deflector:%{HTTP_REFERER}} [R,L]
--- deflector.map ---
## from_page redirect_to_page
## redirect_to_page = '-', then error page from you

The fun with redirecting people back to the original site is that it generates
a quite a lot of extra logs and users may send them angry feedbacks about
broken links.
Have fun...
