I don't think we've seen anything of the flaming that isn't justified, and certainly nowhere near the vitriol that can be directed at folks on some US-based sites (and certain parts of PH, come to that). I can only speak for myself here, but personally I wouldn't want to be part of a forum that actively encourages lazy idiots to be a part of it. That's essentially what you're talking about, people who are too lazy or too stupid to ingratiate themselves correctly into a well-established community.
It's the equivalent of a complete stranger walking into your favourite pub and yelling as loudly as possible "CAN SOMEONE TELL ME WHERE THE TOILETS ARE AND ALSO WHAT DRINK GOES BEST WITH THE CURRY AND CAN SOMEONE BRING IT TO MY TABLE NOW!". You wouldn't call that acceptable there, so why should it be different here? All any newcomer has to do is look around the screen , at least try the search and have a read of a few threads to get the idea of how the place works: It's not rocket science. We get a good 20-ish people signing up every week at least, and 99% of them are capable of doing a Welcome post and being polite, so why should we make special allowances for those who just can't be bothered?
There's flaming, and then there's gentle ribbing trying to get people to understand how this place works. We get very, very little of the former, and the latter is only allowed where it's deserved.
