4.2.1

That's weird, I don't get that message. It sounds like the phrase never got added. Try uninstalling the product and reinstalling. When uninstalling you will need to reupload your files to the server from the zip files upload folder.

You could also add the phrase in AdminCP:
NAME: proxy_alert_registration

DATA: You were detected using a proxy. We do not allow registration from proxies. If you believe this detection was in error, please <a href="sendmessage.php">contact</a> your webmaster.


1.6 has been released:
User ID Whitelist
Bot detection fix
IP Whitelist [PRO]
Registration blocker works with ip address whitelist [PRO]

This is something I too would like to have very much.

EDIT: And yes, how we can enable spiders, especially Google and Google AdSense to freely scan our sites?

Ahh yes thanks for reminding me. As far as the bots the new version allows bots to bypass the checks. If you are still noticing bots being blocked PM me with the name of the bot so I can add them to the white list.

The thread notification is fairly easy to do. I will probably add this to the free version along with the pro. I plan on adding a Database logging through the Admin Panel for larger boards that don't want a flood of PMs/Threads/Emails. Maybe I will come up with a cron job to email weekly when new ones have been logged or possibly even email the log, so that way it is all in one email instead of multiple. The possibilities are endless! lol.

This with weekly email would be nice, but having thread created, for all moderators to be informed is a very welcome option, so we could allow people to use proxies, but watch them more closely.

And, how can I manually add spiders? Through their UA, or differently? I'm still not installing it, as this is very important for me, so I'm waiting to know how to do this.

Yes
Of course if you wanted to just allow a few bots and not all (The ones you know are good bots) then you could just check the user agent for Googlebot or multiple other bots.

This looks pretty complicated. Where it should go?

Would your mod be able to work in report only mod, without actually blocking anyone and just creating threads with users who use proxies?

As of now, no. I can code this feature though. I'm still working on database logging, once that is completed I will work on that as well. Give me a few days.

I installed the Pro version today and used this site http://anonymizer.nntime.com/ to access my site. Do I not have it set up correctly? Because I was able to login...

Testing this promising mod and it successfully denied me access using the TOR browser.

I have a quick question:
I enabled: Would you like to enable Tor Alert for lan proxies?

Now I got several PM's telling me what users are detected using a LAN proxy. I know those users and they are trusted.

Are they actually blocked and don't have access or is it just an info I get in the PM and those users can access the forum?

Thanks
