Registration Fails Spam check

When I register a test user from www.heatmisersaves.com/component/comprofiler/registers there is a spam check question to answer but if I try to create a test account from the HikaShop Registration form the spam check question is not visible, therefore not answerable so after filling out all of the user details it fails a spam check that was never presented in the first place. The HikaShop registration form is on www.heatmisersaves.com/component/hikashop/checkout

The problem is that this spam check checks also hikashop registrations.
There are 3 solutions:
1. modify that spam check to not check registrations coming from HikaShop.
2. modify that spam check to also be displayed on HikaShop's registration page.
3. use another spam check which works for both registration pages. For example, you have that plugin: extensions.joomla.org/extensions/access-.../authentication/7319
It checks on registration without a question by analyzing the data of the registration against online databases of spam and other things.

For both 1 and 2 solutions, you should ask the developer of the spam check.

Thank you Nicolas,

After some checking I opted for option number 3. I hope the free version is good enough for now.
