Spam is annoying. Here's a way to automatically block robots from collecting email addresses from your website.

The code is as follows:

Function security_remove_emails ($content) {

$pattern ='/ ([a-zA-Z0-9.9% a-zA-Z0 -] + @ [a-zA-Z0-9.9 -] +\. [a-zA-Z] {2Jing 4}) / i'

$fix = preg_replace_callback ($pattern

"security_remove_emails_logic", $content)

Return $fix

}

Function security_remove_emails_logic ($result) {

Return antispambot ($result [1])

}

Add_filter ('the_content',' flex_remove_emails', 20)

Add_filter ('widget_text',' flex_remove_emails', 20)

Put this in the functions.php file, and if the robot collects email addresses, it will be automatically blocked.
