CAPTCHA codes

[Mayhem 1]

Gentlemen:

Do any of you guys use these CAPTCHA codes on your sites/email address ?

I am continually swamped out with spam even though my email settings are on maximum to stop spam and after reading about these CAPTCHA codes it could be the way to go.

Your thoughts Gents

I use the one of my other sites and it works well. Was a bit of a pain to get working but it worth it. Really need to get it up on my disco site.

Easy to integrate, recently bought by Google but don't let that put you off!

Personally I don't like them, and I wouldn't use them for the simple reason they may deter genuine enquiries, unless I 'get through' on the first attempt I usually go elsewhere, unless I really want to visit that particular site. I don't find spam to be a real problem, it only takes me a couple of minutes to delete it, and that includes checking the contents of the filtered spam folder, I frequently find genuine emails in there. Before you implement it, I would ask yourself is the time you save deleting spam over a year, worth the risk of loosing a few potential bookings

I detest CAPTCHAs too, so I came up with the Brucie Bonus... :)

Not the most complex piece of programming and certainly easy enough to bypass (especially to those in the know) but to date it's virtually eliminated spam to my account.

Now don't start signing me up to all sorts of dodgy mailing lists you lot ;) :D

I like :)

But I wouldn't want to be JS dependant.

No idea never used that before, but he said it helps stop spam alot

The fact that it uses AJAX has nothing to do with the effectiveness of the CAPTCHA I'm afraid!

I'm making the assumption that you talking about form submission on your website.

I notice you are using a form processor, with basic form validation.

You could modify your script and add extra validation.

You obviously would need to understand PHP to make your mods.

An example is here:
http://www.alt-php-faq.org/local/115/

Alternatively you could just add a new form field with validation that requires human input such as one that i use is "what colour is a fire engine?" and if the answer is red then the form passes the validation and allows the form to be submitted.

This method is easy to impliment as most form generators/software allow validation to be set in this way.

Or lastly find a decent form processor that includes better validation techniques.

You may want to have a look here:

Look for the free ones - there are some good ones here!

Hope this helps as Spam is a pain in the butt!

Anything that requires a human input will stop any remote injection method.

I just use a simple form validation that only a human can enter.

Nice one Vectis!

To send Spam via the enquiry form, a human would have to sit there filling it out, where's it's much easier to add your address to their spamming database, and send it to thousands of addresses via a Yahoo account, for example.

I think adding mandatory fields to your booking enquire form such as
- Telephone Number
- Name

etc, would definately be worth considering, as most of you will already do so.
