I'd expect them to be able to continue with the rules in place, but the four days = one day rule is one that's a temporary check, not a permanent one. If the mod wanted to change it come October after the trial attempt, if others wanted it changed back, then why not?
I think saying "new management, new rules" is like telling people who like the game that they might be stuck with a mod who randomly decides to alter rules that they joined the game FOR, as I know some have joined for very specific rules listed in the game. I'd expect someone who'd want to step up would be interested in keeping the game generally as it is, with fixing things up here and there as needed...
...but again, I wouldn't expect them to go crazy. :\ That's not fair to the people who joined the game while the current rules were in place.
