Hide email in paypal forms

Is it possible to hide emails in paypal classic forms (without hosted buttons?
Some alternatives?

<input type="hidden" name="business" value="EMAIL">

Certainly it’s possible. PayPal gives you the option to use your merchand ID instead of your email address. It looks something like this in the form:

<input type="hidden" name="business" value="THRHENW7RHX9R">

Here is a way to hide email in paypal forms -
<input type=“hidden” name=“business” value=“your.paypal.email”>

I don’t think that’s what the OP means by ‘hide’, as that’s not hidden from spam bots, which is what you really want to hide this from.
