Nothing in those articles reliably supports (i.e. beyond a couple individual anecdotes) the contention that a) the Obama campaign had "no checks" or b) that Romney was rejecting unconfirmable contributions.
"Walker said he used his actual street address in England but entered Arkansas as his state with the Schenectady, NY, ZIP code of 12345."
In fairness, that's fraud on Walker's part not on the Obama campaign's part. There's a limit to what kind of checks you can feasibly do. By the sounds of it, requiring a billing address in the United States seems reasonable.

Actually, this one would've been easy to catch - we know which states have which zip codes. The company I work for checks this in web forms, but I don't find that such validation is common.

Problem is, it isn't. US citizens living abroad have every right to donate.
Actually, I think that zip code is valid :) according to a quick Google search at least.
But I admit I hadn't thought about citizens living abroad; that makes it more understandable there would be these issues. It's certainly a case of (perhaps) incompetence over malice anyway.
Edit: my mistake, I missed that he claimed the zip was in Arkansas.
You would need some sort of photo of their passport to verify citizenship for a foreign national. You would have to securely store thousands of these images for reporting purposes. It would be a legal and technological impediment and extra cost involving a large amount of effort for very little payoff. This was easier to limit with the online store. They just didn't provide international shipping options.
