Hi Alex,

Did they activate their accounts?

No, they didn't...as far as I can tell (coloured RED). I do not see any new subscribers confirmed through email either (which I do receive with genuine registrations, even before activation).

... but still are able to use my mailserver to send emails using my forum as sender...

How do they do that?

Good question...

What can I do about this?

Enable the CAPTCHA for thr register form.

I have.. mathematical as in the past the graphical didn't work in Firefox.

PS , using version 2.14 (not sure if it will be different in version 2.2). I am going to upgrade but the original template changed a whole lot more just to do this "on the fly". My version of MLF looks rather different and I have to redo it all again for version 2.2...

PS, it is more quiet now though (new illegal members 5-10 times a day), I only had to delete a whole bunch when I noticed it (doing research after complains from people who received "my" spam).
