This MOD has been replaced by a better version with ACP support. You can find that version here.
What follows is commentary on the original version, which still works fine (tested up through version 2.0.21). However most users will prefer to use the ACP version because it has more options and is easier to install.

***
This is a continuation and enhancement of a previous MOD. It has been improved by many community members and seems to be very stable. The code below has been tested with phpBB versions 2.0.6 through 2.0.20. A big thanks to the original author niekas for getting it going. Unfortunately he seems to have disappeared, so we are starting a new thread to continue development of this excellent MOD.
The purpose of this MOD is to prevent spambots from registering user accounts on your forum, using spammy URL and Signature fields. These bots do not care whether or not you have account activation enabled because the spammers only want to create a web link from your forum to their website. Bots are detected as follows:
- 1. You remove the URL/Sig fields from your new user registration template.
2. Any user submitting a URL or Sig field during registration MUST be a spambot script, because normal users won't see those fields during registration.
3. Add code to check how many posts the user has made. If it is above a certain number (default 10) then the user will be able to add a URL and/or Sig when editing his or her profile.
Again, I can't take credit for this awesome MOD. It was a community effort, and all of the contributors (to my knowledge) are listed as authors in the comments. For a more complete explanation of how this MOD changed over time, and why various design changes were made, please see the previous MOD.
