At the weekend I removed the requirement for word recognition for the ability to do a post a comment...........The consequence was about a hundred spam comments in a day........

So rather than inundate you with websites for rubbber private parts the word recognition is feature that is here to stay
Prof G thinks most are posted by "BOTS" yep Ar*eh*l*s (UK) A*s*o*e* (US)
