Lack of activity in a thread does not indicate that the system is ineffective.
The content is simply no longer "new" or "trending", and the thread creator has become inactive. If its not new and sparkling others tend to lose interest as its happening with most topics over time.
Traders who earn a living from trading usually do other things than repeatedly posting identical trade setups, such as the 200th iteration of the same pattern.
99% of Traders are losing money Trading. Dont make your decision based on what they like or dont.
Trade it, personalize it and make your own judgement.
Cheers
