In a word: machines do not understand, but people can read "words." For example, you can use numbers, uppercase, or symbolic methods, and so on.

For example, my phone number is: ①⑤⑨②①⑤0②④⑤③.

If you are an e-mail address, you can use full-width characters instead of half-width, or cross use: for example, my email is baidu@gmail.com. This is the "encryption" method that does not affect the reading experience, so that the current crawler is not enrolled.

But because of the current development of garbage crawler foreigners, if this method is popular, or if the Chinese people participate in, this method will fail (full-width characters and half-width characters have a corresponding relationship, so you can "decode" the character into a real email address).

Here are some elements that you can use to copy down later:

①②③④⑤⑥⑦⑧⑨⑩

⑴⑵⑶⑷⑸⑹⑺⑻⑼⑽⑾⑿⒀⒁⒂⒃⒄⒅⒆⒇

⒈⒉⒊⒋⒌⒍⒎⒏⒐⒑⒒⒓⒔⒕⒖⒗⒘⒙⒚⒛

1234567890

Some of the above is OK, at least the individual can understand, the following is the Chinese characteristics:

⊙㈠㈡㈢㈣㈤㈥㈦㈧㈨㈩

One of the three Woolu Qi Ba nine titbits

Here are some tips to read:

1:━┃

2:═║

3:╠

4:╬

0:00

1:†

2::

3:∴

4:∷

¹²³зб0ζηα0

None of the above is a number or letter, which is found in Greek, and is not applicable to universal users if it is not UTF-8 encoded.

0:

1:▕

2:〓

3:▲

4:█

5:★

Of course, because I have no Martian input method on my computer, I can find more interesting symbols.

Need to emphasize that, do not have to "encrypt" every digit, only select part, because we just to prevent the web crawler automatically crawl, or try to avoid the reader to think, so give a clear message. For example, the telephone, the emergence of "ten", responsive readers can immediately understand 10 as "0". However, in order not to affect the author to convey the message to the reader, or mark it as well. This kind of annotation can appear at most once, too much increase the cost of the reader to study, will affect the reading experience.

If you need to use large quantities on the contact page, you can make a small program, which is randomly selected by the system in the "Encryption" font. This can really avoid the crawling of garbage crawler. Compared to the popular way to generate pictures, both the efficiency of program execution and the fluency of Web page reading is an optimized choice. And for the front-end developers, less than a length of the picture, reducing the uncertainty factor, I believe it will reduce a lot of work.
