I like the idea and the effort you have been putting in to prevent spam But Jet cash let's be honest for a moment. Do you really think these account farmers/spammers really care about their English? I think you know the answer to my question. There are literally countless free sources available across the web to learn English from. If these people were willing to put the hard work in they would have used them. What makes you think they will use this service instead of 1000s of other solutions out there? IMO this is just a waste of resources which can be spent elsewhere.
