Antispam not effective

I'm getting lot of spam. The kind of spam is the following (I've copy/pasted):

bvtqescu avdowvdh http://xkataafu.com afoshiod yokbjkdz yttprbzl

Sometimes there is only one of these links for comment, other times for each comment there are dozens of different links.
I'm getting this spam every day. There can be one or more comment spammed every day.

Obviously I enabled captcha. It is not possible to ban the IPs because every spam comment reports a different IP. I dont' really think that this spam is made by a human as it appears regularly every day.

I'm missing some settings? What can I do? Does Chronoengine will update the antispam protection?

Thank you.

Hi Nicero,

the captcha will be updated for ChronoComments, unfortunately its not hack proof because of the multiple instances and the AJAX :?

Good. One of my sites is getting the same kind of spam. The client tells me they've gotten 8 of those in the past couple of days.

Not to rush, but any eta on the update?

thanks.

Hi dang,
