No controls over who signs up

Nanovor lets kids sign up to play this game without parents' permission. Some kid -- I have no idea who -- hijacked my e-mail account months ago and is giving it out as his parents' e-mail. I keep canceling the account, but Nanovor lets his reopen the account with my e-mail over and over and over, even after I repeatedly explained the situation to them. Not only do they not require that the parents verify the e-mail, Nanovor doesn't even require that the e-mail be active; if messages to it bounce back, Nanovor doesn't cancel the child's account. It's a good thing the content on this site is mild, because there are absolutely no controls on it.

Squicky goo, but otherwise fine

Only just loaded this, but pleased to see you can limit the chat functions and also parents can join as friends of the children, so we can see it for ourselves and help out with trading, etc to boost their scores. The "good guys" seem to set a good example. Only drawback so far - the graphics when the bugs are defeated are rather squicky (but green goo, not blood-style). Wouldn't recommend for littlies, but 9 or 10 upwards will love it.
