How can deactivate a request-form?

Hi Support Department

You need to customize the Guide Theme for that. It's documented pretty well here:

Thank you for your response. I believe you're referring to the second 'custom theme' section in the linked article. Meaning, I would need to edit the standard theme, e.g. by removing the request-form page? Keeping the request-form page, but 'hiding/commenting-out' the request form {{request_form}} doesn't change the situation. The spam-bot can still send requests via the web-form.

Yes, that's how you'd need to do it. The spambot cannot use what's not there.

Shouldn't commenting-out {{request_form}} already do the job?

That depends on the bot's "intelligence": If it caches previously accessed URLs, then having the form available at the old location will make it available to the bot.
If it just crawls your page, then commenting out that section will be good enough.

Ok..so this is an 'intelligent' bot. In this case, is deleting the web-request page 'new_request_page.hbs' be the solution? Or do I have other options?
