In order to sue this basher here is the way.

There is a way to find out the IP address of a member of a forum even when that forum's moderators are uncooperative, and it doesn't mean hacking the forum or anything like that.

I've done it recently to a member of a forum recently on accident and realized it afterward. Here's how.
I have my own website, which logs all http accesses. I used the forum's private message feature to send a message to the specific person, and inside the message embedded a picture hosted on my website. The address of the picture isn't revealed to anyone or posted anywhere else, just put in the PM.
Later check your website's logs for accesses of that picture file from ip addresses that don't belong to yourself. That would be the accesses from the forum user of whom you are gathering data for. (Or a nosy forum admin reading people's private messages)
In the log of your own website, filter down to that one picture filename, and it will tell you the date/time accessed, IP address, browser and OS type & version. You can look up the ip address on some websites to tell you the hostname and often approximate location (what city).

After investigating all the bashers then assemble the culprits into a report showing the main contender.

If nothing else, at least we can let these clowns know they are messing with fire!!!
