Proxy Blocker Mod by simmaster07

Compatibility:
SMF 1.1
SMF 2.0

Configuration:
SMF 1.1: Features and Options
SMF 2.0: Configuration > Modification Settings

Killswitch:
If you are blocked from your own forum, add

Code Select Expand

$kill_proxyblocker = true;
somewhere into your Settings.php file.

The Proxy Blocker mod allows you to disable users on proxies from registering or viewing the entire forum altogether. This helps prevent banned users from trying to re-register, or spambots from trying to use proxies to attack, with the disadvantages of blocking school/corporate connections that use proxies, cell phones and primitive browsers.

Tested on proxies:
* HideMyAss
* ProxEasy
* The-Cloak
* Proxify
* WinkProxy

Tested on browsers:
* Google Chrome
* Mozilla Firefox 3.5
* Microsoft Internet Explorer 8

This mod makes no template edits and should work on all SMF 1.1/2.0 forums on any themes that aren't modded excessively.

Sounds useful.
Have you tested it on http://www.torproject.org/ ?

[Arantor]

* The Grinch thinks it probably wouldn't work on Tor because of how Tor works... but hasn't tested it on that. I just tested it on The Cloak and the above two.

[BrianVB]

This is really a great mod, thanks!

[DoctorMalboro]

I ♥ U!!!  thank you soo much!!!

$txt['on_proxy'] = 'Lo sentimos, el administrador bloqueo el registro desde este proxy. si usted nunca tuvo acceso a este foro, el problema se debe a una conexión local, uso desde un celular o imcompatibilidad por parte de su navegador.';

[Arantor]

English-UTF8, English_British and English_British-UTF8 all use the same wording as your existing one, btw.

You can check for this by looking up tor-exit in the hostname.

Really, between that, this and say, checking for IE 6 or under, you could stop most spam by requiring such users to prove that they are human. I don't really want to block such registrations entirely : /

[simmaster]

Thanks for the translations. They will be added ASAP and will add them into the next patch (1.0.2)

@Vekseid: It's not just the fact that they need to prove that they're human. Some webmasters (like myself) would prefer blocking proxies in their entirety so banned members don't rise from the dead, spambots don't attack continuously, etc.

@The Grinch: I will test it on Tor and post my results. If it fails, I'll try patching it up.

[Vekseid]

Yes, but if I wanted to block all access I would have done years ago.

Err, just match for tor-exit in the hostname, I mean. You'll want to do a hostname lookup for that though. Tor exit nodes don't have port 80 open.

Well, it's not really that hard to do a hostname lookup. Thank you, gethostbyaddr()!

[Arantor]

You could even cache the hostname into a variable instead of calling it multiple times, just as a thought.

Proxy Blocker 1.1 should be out within the week.

I really like to see this mod for 1.1.11, according to the small code, I hope it's not too much work??

[simmaster]

It's working with 1.1.11 and should be out later in the day. I just need to fix the issue where blocking the forum blocks everyone.

great I will look forward to it and will test it at a very busy  board

[simmaster]

Before I release 1.1, can someone translate these strings into Spanish:

Code Select Expand


$txt['proxyblock_reg'] = 'Block registration if using proxy';
$txt['proxyblock_index'] = 'Block forum if using proxy';


No, I didn't fix the issue yet.

[Arantor]

Btw, someone has just commented that the edits to the language files should really have a new line above them to prevent run-on from the previous line.

No biggie, just would be good to keep tidy.

Noticed that myself and fixed it in 1.1.

[simmaster]

Proxy Blocker 1.1 is out and fully functional, with the exception of Spanish language strings, which still need the two new language strings translated. Major features are blocking the entire forum, blocking Tor nodes and SMF 1.1 compatibility!

[qtime]

great news!!! I will test it within a few hours, I asked for a spanish member to help to translate, unfortunately no responds, yet...
