Removing Information From Google Search Engine

Even if you do add the required code to block search engine bots, there are still malicious bots that doesn't follow rules that will index your information.
Publishing your information on the Internet is a risk,

You might be true in saying that publishing your information on the internet is a risk but I must say that there are a lot of ways to protect your private data. If a page is published publically, it is meant to be indexed by bots (without the discrimination of good and bad). All bots are meant to index the published page and data which is confidential should not be published publically. If a person publishes private data publically and later on complains of risk of publishing information on the internet, it is his fault not internet's.
The first line of defence for keeping private data confidential is to block indexing by search engine bots. If we assume that the quoted text is correct, even is such situtation at least the good bots will avoid indexing the page and making it public. And let me tell this here that most famous bots are good bots. So even if your webpage is not indexed only by good bots, you still recieve about 80% protection.
The second line of defence, which targets the bad bots is password protected pages. They are totally under your control and cannot be indexed by anything unless they know your password or crack it. So yes publishing your information on the internet is a risk but it depends on you that how you publish it. If you do the things correctly, it is not that much risk but if you don's give a damn to doing things correctly, you are at a big risk.
