I have a certain soft spot for the 'free move.' It allows people who are new to the game to get more used to it and move to a region they more appreciate. We should still retain some newbie-friendliness.
Unfortunately it also has the potential for great abuse, which is why I'm conflicted. However, if people are going to vote stack, I'd imagine they'd do it in the initial registration, and not necessarily in the free move.
It depends on whether someone is recruited for asshattery from outside the forum, or right after he registers. Either is perfectly rational and has happened in the past.
There is currently no such thing as a legally defined thing called a "free move" though, and absolutely no argument for creating it. If you want to stop people from moving between the 8th and 180th day after registering as well as within 180 after moving, it would be wise to write an amendment that simply says so.
