Doesn’t work
by markrbower·8 months ago·1 reply

I think it used to work, however now it shows the error if you get the captcha wrong, but still registers the user, so it’s useless against spam registrations. I say it used to work, as my site didn’t get many spam registrations, but recently I got 30 overnight, so I’ve had to turn registrations off until I get an alternative arranged. I switched it back on to test one more time and instantly got a spam registration, so don’t bother installing this any more.

Fine! The most important thing is that it works unlike the rest.
