On the question Stack Overflow is doing me ongoing harm; it's time to fix it! there was some activity.
As indicated per homepage activity by a user.
So I clicked it and wanted to know what's going on.
Nothing —
visible to me changed.
So I thought, "Ah well, another post censored and deleted, poor low-rep-me will never know…"
But after inspecting the timeline I saw:
2019-12-18 20:39:27Z history notice removed Adam Lear♦
2019-12-18 20:27:52Z history notice added House- 'Reinstate Monica' -man Draw attention
Why was now that bounty removed? So quickly? Without explanatory comment?
Users invest their rep — in this case 500! — to "draw attention" and someone with power to push buttons just removes it? Usually, even questions about to be closed are protected from such actions by having a bounty.
What is the basis for such actions?
