Would you mind posting links to the unhelpful behaviour you have seen on mailing lists or IRC (http://ircbrowse.net/)?
The reason that I ask is that I'm concerned to hear more and more reports of such behaviour, but I've never seen it on the only Haskell mailing list I read (haskell-cafe) and I can't remember seeing that kind of thing on Haskell Reddit either, at least not without a number of helpful replies alongside unhelpful or dismissive ones. I'd like to see where this sort of behaviour is arising and see what I can do to improve things.
