Trolling debate - should you "feed the trolls"?

I have absolutely no idea why the GBs waste their time trolling here or VB. I can't imagine it's very entertaining to snicker about us behind our backs.
 
I don't think it's ever construed as "behind our backs." Just uncensored and un-oppressed opinions of goings on. Some of it very snicker-worthy. I haven't been over there in years, but discussion of other boards had hardly been a dominant topic of discussion when I was there.
 
It's the same in the U.S., except they're very good at hiding the cameras from plain site.

I was amazed at how fast they were able to identify the Boston marathon bombers.

It is the same thing in the UK. When there is a murder investigation, they seem to have all the latest
wherabouts and details of what the person has done, bought etc.
