Regular users marked as bots on short forms

Problem/Motivation

When form is quite short and visible at the start such as login form, that does not need scrolling through on mobile to see both inputs and submit button, the user submitting that form was marked as not human and was redirected to /antibot page.

Steps to reproduce

Have a short form on a page, and submit it without scrolling on a safari browser

Proposed resolution

Add touchstart to the list of events that unlock forms for humans.
