Obviously they are still here as shown by the recent deleted first post in the alerts section and the moving of a thread here to the sandbox. However, both were done without the normal post from the mod doing the work offering a brief explanation for the change.
Also, there seems to be a growing backlog of unprocessed reviews.
I am aware it is a voluntary position, but it does seem odd to continue to post in the welcome section as ffireman did yesterday while such seemingly strange behavior is afoot.
On several occasions, I have offered to lend my community moderation experience to the staff here. This time I do so publicly, as it appears assistance is needed.
