The way to improve the S/N ratio of this newsgroup is
for people who
begin threads, to think long and hard about how their threads can be
hijacked by trolls, and never start threads that are vulnerabel to such.
Make a pledge (within your own mind) to only start threads that are
substantial, constructive, and not vulnerable to hijacking by trolls.
We would end up with a completely silent mailing list. A competent
troll can hijack any thread...
