This task is very simple if know the software:
1. Currently Getting High Amount of Users Join from China and spam with software - We have IP Banned however would like other suggestions to help reduce this without doing an IP Ban as we have users based in China which this causes problems.
2. New Users - We have new users join then Spam the forum we want to stop this and make it users can only post once maybe twice within 24 hours.
3. Other suggestions for the forum with linking to wordpress and facebook
Version (vBulletin 4.2.0 Patch Level 2)
We have ongoing work like this if you are good.
