Let's talk when your sites disappears permanently, shall we?
My sites don't disappear, never mind permanently. Never. Not in almost 10 years - not since I started. They don't even get algo bans.
But apparently the people that frequent this forum seem to think that makes someone inept. Personally I think if you're looking to succeed, then asking the local failure isn't quite the way to go. Right up there with asking the local homeless guy for money making ideas. Well, he's failed so he must know what he's talking about. Personally the person I look to for a business mentor is on his way to becoming a billionaire, and he never fails.
Just because you didn't plan or account for this doesn't mean I don't know how to build my business so that it's proof against this stuff. My rankings prove otherwise.
