Filtering words in text string

I'm needing a functional solution for a system I'm doing.

I need to block the textarea field record if it contains some words in the string, eg:

This is a brief description of my profile, my phone 33 3333-3333, my email: [email protected], and my site: www.mysite.com or myite.com

I want to block, that is, not allow these items in the string, I do not want any type of contact, neither phone, nor email, nor website, nor facebook nor any kind of social network.

It can be a solution in Javascript or pure PHP, which is as simple and objective as possible.

I'm waiting for a return from you!

There are a few ways to do this, a basic way would be.

$('textarea').keyup(function(){
  var texto = $(this).val()
  var email = /^[a-zA-Z0-9][a-zA-Z0-9\._-]+@([a-zA-Z0-9\._-]+\.)[a-zA-Z-0-9]{2,3}/
  var telefone = /^(\(11\) [9][0-9]{4}-[0-9]{4})|(\(1[2-9]\) [5-9][0-9]{3}-[0-9]{4})|(\([2-9][1-9]\) [5-9][0-9]{3}-[0-9]{4})$/

  texto = texto.replace(email, 'xxxxxxxxxx')
  texto = texto.replace(telefone, 'xxxxxxx')
  
  $('.result').text(texto)
})
