I just declared v3.hmotaku.net as $http_host; ($http_host = 'v3.hmotaku.net' and in result all requests from forums.hmotaku.net (the real forums domain) was blocked by "POST requests from foreign hosts are not allowed." What happened was that all requests were blocked; EXCEPT from v3.hmotaku.net; which was declared at $http_host. So I declared forums.hmotaku.net $http_host as well, and all was fine again. -_-;;

I'm not sure how the whole referer checking thing works in vB; but how exactly did I loophole it? And NO, any other site can't submit; as proved above. =__=;

you loopholed it by over writting what ever hot is really submitting... the reason urs did not work is because the subdomain of main site used in $http_host did not match your forums domain. so basically by setting doing the edits you did, you over write who/what site is really submitting making your site vulnerable. What you should be doing is checking the $http_host first to make it its your main site submitting then change $http_host if it is your main site. Do not under estimate the checking because this helps keep your site secure from malicious hackers and websites.
