Well, let me put it this way: if someone (say, Admin Example) reverts a block on a given troublemaker for whatever reason, then the troublemaker becomes that person's (i.e. Admin Example's) problem. The Admin who blocked the troublemaker in the first place should be allowed to go on with her/his business on Wikipedia.
That's my opinion on the matter. YMMV.

It sounds like the Admins need a coordinator or manager. I'd be happy to volunteer for that job. (Any Admins who want me to manage them, email me or leave me a note on my talk page.{
I've already taken on the role of Coordinator by creating and maintaining [[Wikipedia:Account suspensions]]. It survived a vote and has received community approval. A number of Admins have used it.
It's for those cases which are not clearcut: things other than "simple vandalism" or "3RR violation". Anything where you're not sure enough to do it by yourself, quietly, but you don't want to make a big arbcom matter out of it.
