These 2 plugins decreased the spammers from about 40 to 0 per day!!!
The second plugin needs some monitoring.
In my case, most spammers ran thru the registration process in less than 3 seconds!!!
Including reCAPTCHA.
I have set the walk thru time of the registration process at 30 seconds.

I have those 2 plugins now for over 1 month, and they are working perfect.

Do you have links to said plugins?

Thanks to both of you! working on the 1st suggestion right now...
