Think of a few flaws in the current blog sites and search engines

I'm bored. I just went to the homepage of the Chinese Blog and wanted to see if there is anything better. ArticleYou can see what you have written. It is displayed in a prominent position on the home page. Should I be happy or should I be unhappy? It is reasonable to say that it is a good thing to recommend your log files to the homepage and be browsed by many people. However, I wrote this log to myself. I don't want many people to see it. I should be unhappy. So I don't know what I feel. I have already posted my own logs on the homepage, or my own logs are reprinted elsewhere. Every time, my heart is quite contradictory. Haha.
Maybe every blog site will consider this issue in the future. When you add logs, add an optional item, "Can this article be reproduced at will ". If you explicitly state that this log cannot be reproduced, do not reprint it.
Think of a search engine. Many Web pages do not want to be searched by search engines. For example, some confidential information, internal files, management pages, and so on. Then there should be a standard that all search engines must follow. According to this standard, you can clearly tell the search engine during the webpage writing process that the webpage does not want to be searched. Unfortunately, it seems that there is no such thing.
Copyright and privacy issues on the Internet have always been tricky. I believe these problems will be solved in the future.
