I once saw a similar sell off as several members threw in the towels, I actually asked some other senior members if something was going down due to all the clack sales, and of course they hadn't heard of anything.
Months passed, the sales slowed down and it became a ghost town with no one selling clacks. Then there were a few CC sales, and everything picked back up. Ebb and flow...
We know this
1) clack continues to have high success selling his clacks
2) these sales technically end in less then 1 second, with thousands of people missing out.
3) some of the other senior members who have run into life difficulties are reducing "SOME" of their collections.
I myself contemplated selling off some of my more valuable items to raise some cash for some big expenses (ie. baby, insurance costs, possible new hobbies ie. cycling)
Fortunately, I've withheld myself from quitting my current job. I just needed to cut back for awhile.
