I'm using this and the reCaptcha, and have had no spambots since. I'm running 3.8, and it seems to work fine.

If your on 3.8 then you should at least be using the 3.7 version of NoSpam!.

For some reason I've tested both and it won't allow anyone to finish the registration process. I'm now using the built in version and so far no spam.

When you had NoSpam! installed, did you have the built in questions disabled?

Yes I did? Could it be case sensitive?

I don't think it's case sensitive, but you did have to include variations of words if you wanted those variations accepted. Plus you had to format them correctly in order for them to work.

This worked perfectly for months and as of a couple days ago they are getting through in waves. I think they're on to us... Time for an update.

Same happened to me - been great for months then last couple of days waves of spam accounts.

i assumed that the robots had got more clever and were able to understand simple questions like

2 + 2 =
and
Type XXXXX here

I initially just replaced the questions with ones very similar just different figures. Seemed to work for a couple of hours then they came again.

So I then replaced the questions with ones that didn't have the answer in them - like

how many fingers on one hand ....

what is the opposite of North ......

What is the talest mountain in the world .........

Since changing these all spam accounts have stopped. Dunno if its coincidence but I'm happy either way

Cheers, good to know.

Yes I seem to be getting waves os spam accounts alot the past couple of weeks, it would seem they have found a way around Nospam and Captcha
