Fact of the matter is that the registration engine for this forum is dated software and does not take into account all the new robots (and don't believe for a second that "barati" is a real person) that automatically and autonomously register for websites, and spam its users and forums.

This is why image recognition technology is now used for these types of registrations. IR is something that simple script programs cannot handle presently. (I'm sure nefarious butt is working on defeating these systems, if it hasn't already been done)
