html only:

<p>If you want to get in touch, please drop me an email at<!-- fhetydagzzzgjds --> email@<!-- sdfjsdhfkjypcs -->addr<!-- asjoxp -->ess.com</p>

or html+css:

<p>If you want to get in touch, please drop me an email at <span class="blockspam" aria-hidden="true">PLEASE GO AWAY!</span> email@<!-- sdfjsdhfkjypcs -->address.com</p>.

Then, we use the following CSS style rule:

span.blockspam { display: none; }

You can disable all form elements in a fieldset by setting the disabled attribute on the fieldset.
