So the amount of forum accounts that have been registered recently to spam/increase search rankings is kind of ridiculous. I even added the registration question that a lot of people struggled with ("What is the answer to life, the universe, and everything?") back in, and I had like 5 new spam accounts registered just this morning. I also have captcha and a couple other questions as well.
I'm pretty sure it is real people registering accounts at this point (a lot of accounts are registered in India and China, where labor is cheap). I'm not sure what to do to cut down on this. How do I stop humans from registering when they're registering for spam purposes and not make it a huge hassle for legitimate humans?
