Spam in K2 comments

Hi!

In the last days my sites are receiving a lot of spam comments, despite I have Google Recaptcha enabled in K2. Comments are open to guest users, and I need it to be this way.

Could someone tell me some good Joomla extension to control spam in K2? I don't mind to pay if I can use it in all of my sites, but if it's free, the better

Thanks!

Hi.
Sure as you noticed ReCapchta can be broken since 1 year.
There are few other solutions, some people uses comments from facebook API.
Some others additional extension which may help.

Comments are open to guest users, and I need it to be this way.

It means that you will always have some spam comments.

Did you thought about IP blocking ? Probably you don't needs comments from few countries.

Other solutions you will find here: http://extensions.joomla.org/extensions ... protection

Third solution - which I suggest in most cases it would be replace ReCapcha to other "protection" but this required installing:

Instead of guessing symbols, KeyCAPTCHA offers visitors to complete an easy interactive task.
You can start with the free version and if liked it so much you can upgrade to the paid version, $24/year

or
K2 customization
- both methods are worth a try.

Can you please give me some suggestion about K2 customization you mentioned?

Thanks in advance

Sorry, but in general we don't help with customizations.
But please check on official K2 forum, there are few topics about it, I remember.
