Kilo11,
Trust me, we've been there, done that and even got the t-shirt.
Unfortunately, this has always happened, and nothing can really be done to combat it short of what we've tried in the past or currently do.
Such is the nature of "request" forums.
It can be frustrating, but it certainly hasn't reached crisis point, nor has it decreased our visitor numbers due to frustration.
All we can really do is grin and bear it. People are people. If you try to stop them being people, things either get very ugly or very lonely...
