"If indeed his site was hacked, why would he put in a number one digit off if it is his real domain?"
If I were a scammer, I wouldn't go anywhere near buying a domain name with my real name, my real credit card number, or my real phone number -- and I would probably pay the extra $5 or so to hide my fake registration information through a proxy buyer. The fact that the phone number is off by one digit doesn't really convince me that he's a spammer (unless he is an incredibly foolish scammer, in which case he will likely get his due soon enough without your hassling him). I think a typo is a far more likely explanation -- especially because changing a single digit in a phone number is a really pathetic way of spoofing data.
The domain name itself is also not conducive to scamming. He could at least have chosen something a little bit less personal than I Ronald.org. I think it's far more likely he wanted to use the domain as a personal site. (Or someone wanted to make it look like his site.) The better scams I've seen tend to use legitimate-sounding domain names that one would associate with a scam. The only reason I can see for using something like ironald.org is because it was on a server left conveniently undefended.
If you really feel the need to be an upstanding citizen, you could contact his site's host (though they seem to be aware of the issue already) or the FBI, who are far better equipped to dealing with scammers. I also find it unlikely that the scammer pulled the page because he was looking at the referrer logs and reached this site -- my instinct would be that the page was pulled because someone reported it to the host of ironald.org, who then changed the permissions on the directory to prevent people from being scammed while maintaining the evidence. I find this more likely than the alternative explanation because if I were a scammer, I would prefer to keep my link up and simply filter individuals referred from Cprogramming.com; why waste the leads from the advertisement, if at all possible? (If he were a true amateur, then perhaps the mention of threats to call him or submit his site to Paypal's abuse department would cause him to pull the page. Then again, I find it hard to believe a true amateur would be checking the referrer logs.)
