Set your status to invisible.
That's completely unrelated. The LS list is not only slow to update and can miss people when zoning, it also has to be activated manually. It would be a big improvement to simply see it in the log when someone comes online so you don't have to check every two minutes.
This is another one of those things that literally have no downside to anyone. If you don't wanna see others, filter it. If you don't want others to see you, set your status to invisible (which is what you'd do in that case anyway, I presume), or SE could possibly even add an additional settings property just for that. It's something many people would want and something that has no negative impact to anyone who doesn't (because they could change it so it behaves exactly the same as it does now).
