I need the commands that work with the new 7.2

1. Find out who posted and or registered from a certain IP

2. Find certain words in the PM database to see if somone is spamming or soliciting

3. To delete PM's containing a certain word

4. To delete all PM sent by a certain user

Does anyone have any good tip on how to prevent and eliminate Spam in PM's?

The censor feacture is pretty good... but how do you censor if people try to spell things different... like c e n s o r or
c
e
n
s
o
r

or how do you find out if those are being used in posts and PM's? The search feature can not look for c e n s o r



Thank you very much
