One of the first off topic thread before thread lock is implemented. The post has 122 responses in total.
If the same post were to happen today with current policy, it would be locked after the 12th reply is made, axing 110 responses. (90% of total engagement)
I have made a nice little chart for you. The x axis represents the response in sequential order. The y axis represents the days to previous reply. The redline is the cutoff for current thread lock threshold.
