Block MediaWiki spam
Problem
Spammers are trying to get through to my site statistics. They're pouring http links in every hole they can find. How can I prevent this spam?
Solution 1: Block specific http referrers
Add this to Apache .htaccess:
RewriteCond %{HTTP_REFERER} ^.*(tvsetmp3|freeliveporno).*$ [NC]
RewriteRule .* - [F]
This will send an http status code 403 (Forbidden) to requests with HTTP_REFERER containing `tvsetmp3' or `freeliveporno'.
Solution 2: Block http links added to path
Add this to Apache .htaccess:
RewriteRule http: - [F]
This will send an http status code 403 (Forbidden) to requests with an additional http: added to the url path, e.g.:
http://www.fvue.nl/wiki/Article_http://link.to.spam.site
Solution 3: Block http links added to query string
Add this to Apache .htaccess:
RewriteCond %{QUERY_STRING} http(:|%3A)
RewriteRule .* - [F]
This will send an http status code 403 (Forbidden) to requests with http links added to the query string, e.g.:
http://www.fvue.nl/w/index.php?title=Article&from=http%3A%2F%2Flink.to.spam.site
