First off, I entirely agree with your main point. In general with anymore of business, I am skeptical of anyone who doesn't include a real name or location.

However, a side note – does that email obfuscation really work? Looking at what it generates, it would be really easy to detect that it is an email address. Thinly benefit I can see is if the crawlers just go for low hanging fruit and don't bother with the modification. But if they wanted to, it seems trivially easy to still accurately pick out email addresses obfuscated that way unless I'm missing something.
