Well, at first I came here for the babe gallery, a few babes threads and that's it. No contribution, just lurking around.
Then I started contributing with babes uploads, tags and reports and found it quite interesting as the staff was responsive.
Forum then started to be appealing and I posted a few, mainly in the others forums (lounge, feedback mainly) so that today, I first come here to check those forums and, if I got spare time, tag/mod a few pics while enjoying the view. I don't contribute much in the babe forums, only the other sections, so, if porn was gone from here, maybe I'll stay a bit and see how discussions go but can't say for sure I'd stay forever (maybe that's because I'm not an old veteran member).
There are still more things I'd like to do here, like trying to create more threads but, as Honda said, it's often hard to invest time in that and end up having no answer
I think people do no behave the same on the internet as they used to because the demographic evolved. 5-10 years ago, internet was still built by small and real communities that invested time on what they did there. Now, everyone has access and understand the internet and there is way more people just taking what they want without giving anything because "hey, someone else will do it for me". Those people will never answer in your thread and may be the vast majority of the members.
So, if porn was gone, maybe the core of these forums wouldn't leave but a big part of members would. After all, WBW is mainly a babe site.
Also, I think we can merge the two idea of threads raised here and ask for a "Bangledesh in leggings" thread
