Locking threads will only make them sink and this can be forgotten so I prefer the current state and the many threads about gambling addiction.
And then a new thread with the same topic will emerge. The thing about the discussion is that, the topic has variation but when discussions go on for too long, they often get sidetracked and end up talking about irrelevant things and ends up focusing on gambling addiction and gambling being an entertainment and not the way to earn money for a living.
