Currently, there is a contact form on a site I develop, with a dismissible (bootstrap-style) alert below the submit button that says
And when it is closed, a cookie is stored to remember that the user has dismissed it, so that it is no longer visible on subsequent visits.
However, the vast majority of emails has been from web developers looking to be hired to "improve" or "remake" the site, so it appears that this user-friendly and professional notice is not sufficient to deter them from contacting.
The owner has asked me to do something to stop this, like saying on the contact form "I do not hire web developers", but I wasn't sure if that was considered professional, or even inviting, and might discourage legitimate potential clients from contacting.
While keeping the site professional and user-friendly (by not coming across as too aggressive or inconvenienced by being contacted), how can it be made clear that the contact form is only for potential clients, and not for people looking to be hired?
