What makes you say that Google claims it's not true? Google claims subdomains are completely two different domains and you'll lose all the linking/page rank stuff according to their own docs regarding SEO. Some SEO gurus claim it's not so black and white but no one knows for sure. The data does show having docs on subdomain is more harmful to your SEO if you get linked to then a lot.
Thanks.. Trying to understand the issue bit better if you can bear with me..
Let's say you manage to install some cloudfare equivalent in your Vps so your hands are clean. That still exposes the provider systems up to that point, eating up resources?
Or they'll still knock you off and ban your IP at the first point of entry itself..
Cos where that leads us is subscribing to cloudfare type service almost becomes inevitable.. You can't get around it with some free software running in your own box.
EU electricity market is very similar to it, but interconnected and probably more free market style. A lot of people pay the spot price depending on county and their provider of course.
Then you should also know the way they run their energy network is similar to our euro free energy markets. Many many people in Europe pay spot price, the kind that people on HN freaked out when the pricing went crazy is pretty normal in EU.
