This is what I've been also thinking - right now I give a bit too much power to some. While I do trust their feedback (or at least I do in most cases), giving them certain power can harm (power corrupts).
Yet I didn't get to do anything (laziness and more), hence my trust list is unaffected for now. But maybe that will change. My initial plan was to just do some trimming here and there, but getting full cleanup looks appealing too.
