No, we have had posts saying that people lurk, read without contributing anything and then report people who annoy them. I can't understand how anyone could admit to this behaviour, but they do,
To me, this is a community, which relies on everyone to post, contribute and be part of it, but obviously, as in life, there are those who expect others to do the work whilst they just criticise. I have no time at all for people like that (online or off) but it is clear that many people are perfectly happy to allow others to pay in whilst they take out. It's just how it is, I suppose.
