What? Email through their site, rather than wait on them to post contact information? Isn't it better to do THAT, then the latter? Or are you talking about the charging thing?
Either way, moderator or not, people do make money regarding WP outside the forums. It's not a bad thing. I'd name names for examples, but really I don't have too... You all know one person on here, "staff" wise that charges for his services outside the forums...
I usually help for free, but really after a while of doing free work all the time, it's abused. Hence for me taking a break for longest time. Since being on here the past couple days, I've already been getting hit up on Yahoo Messenger for help and via email requests for it too. But again, it's not a sin to earn some money when it's regarding WP installations, and such.
Especially if it's requested by someone, for paying, or for free. It's the "time" spent of the person doing the actual work "installing/upgrading" and what-not. It's their internet, their time, their bills that need paid, and their choice.
It's not to be mean, or disrespectful. The person said they were willing to pay a price, I left my email address and said we could talk prices via email off the forums. That's not a bad thing. It wasn't intended to start a bidding war either.
I left my contact address, made a comment, and it was deleted. Either way, this whole discussion shouldn't be on here. I'm sorry, I should have sent email to the list, or privately.
