You know, I find that hard to believe too... why would you do that even if you did disagree? All types... But as has been said, we are big and ugly enough to cope I think. I've had a few too, one bloke who didn't get his membership approved right away, turned out I'd accidentally deleted it thinking he was a spammer (not much info on his profile to tell me he was genuine). He emailed with this long abusive whine and so I took the time to respond and explain things to which he let fly again. These days, I don't waste my time. Give me a hard time and you can go jump. Why would I bother?
And yes, more people online. Now that IS curious, I wonder why? And the post rate is much higher too. Still, gives me a lot more entertainment at 6 AM that's for sure...
