Use [randomtext] shortcode in the editor to generate a loremipsum text, you can customize your random text in this way [randomtext type=gibberish amount=30 format=ul number=1 number_max=2].
This plugin uses the APIS of http://www.randomtext.me/
A special thanks goes to Dale Davies (http://www.daledavies.co.uk/): without his randomtext.me (http://www.randomtext.me/#/about/) all this would not be possible.
Thank You.
