Don't you realize that the more you, and others like you, police the quiz sites and moan, the more others will answer questions. It's a bit like John Sargent and now Ann Widdecombe staying in Strictly - the more the judges moan at them, the more the public support and vote for them.
Actually, no question has yet been asked on here - cfac knew the answer but just wanted some help in figuring it all out.
You say that charities lose out because some people won't sent off for the quiz but, again, they don't have to look at these sites. Also people who might find cryptic quizzes hard and NOT send off for them, perhaps do so because they know they can get help. So it probably all equals out as far as the charities are concerned.
