I have been noticing a whole bunch of new spammer accounts being registered on this site recently.  I have been deleting them, and I even raised the CAPTCHA verification on the registration page to “extreme” level, which I personally find to be very difficult to read (and annoying).  They also had to pass a simple question, such as “what color are blueberries?”, “what color is snow?”, etc.  Still, they were signing up, which means they were able to pass my security measures somehow.So, I figure that I will change the CAPTCHA back down to simple, and make the security questions a bit harder – questions that a high school student or higher would need to know, and something that probably would not be known to random people living in Pakistan or India.  Hopefully, this will help quell the tide of spammers signing up.
