According to any website owner, their site is listable.
That's generally true. For ODP purposes, that can always be assumed--then must be immediately discarded as irrelevant.
That's why there's no point in discussing individual sites with their owners. They want a listing, nothing else. We want to build a directory to ODP standards, nothing else.
There may be some common ground, some common interest-- but the website owner can't be relied on to recognize it. That's why the communication goes only one way: the website owner states his interest ("consider listing this site.") When he's said that, he's said all on that subject that will ever be needed or useful.
But there is no reason to respond. Remember, the webmaster doesn't have anything significant to say. "My site is listable?" That's not a significant fact, they ALWAYS say that. So every time you review a site and don't list it, then mentally carry out the required conversation. Pretend you heard the webmaster say "I want that site listed." Then pretend to reply, "that's OK, but irrelevant. All that is allowed to matter in ODP editing is the ODP guidelines."
Pretend to get harassed or even stalked about 1% of the time, also, if you want this to be a perfectly realistic imagined scenario.
[added] Simultaneous posting, I didn't intend to correct Jim. Obviously we have different ways of describing things, but also obviously, it's the same reality that we all must face.
