[support] Captcha and spam issues

[Pia Oliver]

I have two live sites hosted at Hostgator.com and one development 
site. All 3 are drupal7 sites and all webforms, forms of any kind are 
set up with Captcha 7.x-1.0-beta2; Image Captcha 7.x-1.0-beta2.

All 3 sites's domains are registered at GoDaddy, the 2 live sites 
have the name servers pointing to  Hostgator. The dev site is under 
Hostgator's "domain" ie the numerical URL and "~/pia". The domain 
name is live  and an old site is still up there.

One live site uses email addresses in a combination, some ending in 
".net" which are processed through Godaddy; the ".com" processed by 
Hostgator.

The sites were previously hosted at GoDaddy and had no issues with 
spam. Since hosting with Hostgator there is an ongoing issue with 
Spam. Even though the forms are **all** have Captchas enabled, 
submittals of the form are happening and I am getting floods of spam 
telling me that gibberish so and so has applied for an account. 
Occasionally, I get a filled out actual form where the different 
fields are filled out with gibberish or URLs pointing, mostly, to 
pornographic sites.

How is this happening? I have been told that robots are not capable 
of deciphering an image but possibly math. That's why I have changed 
every single one to image captchas.

I have talked with Hostgator numerous times, but so far they have not 
been able to solve this. I have even been warned by them of all the 
spam!
