It was I who suggested it. I'm fairly certain signups are made easy, to generate traffic to the website to make the website more Proffittable. One of the reasons why the site went from mostly professionals, to mostly customers/ people wanting to do their own stuff . It brings more traffic to the site... But is a short term gain, long term loss in my opinion
The software I suggested keeps bots out, while the end user doesn't notice anything different at all. Win win for both sides.
I don't think it's been implemented yet... So maybe admin is busy. But this is a pretty big problem that keeps getting worst... So hopefully he can make the time.
