"Gamers will not be thrilled that this issue looks set to become hot, while the other far graver oversight continues to languish unattended," Carago said.

"I'm not sure that a 'crackdown' will serve any purpose whatsoever, other than to highlight what we all already know: That we will continue to flail within a system that is hopelessly flawed."

" and I just don't see how the Government can be nimble enough to cope with the large number of apps submitted on a weekly basis," Dawson said.
