If you want to earn activity, then you can't take a break, though potential activity can be earned with periodic posts. Otherwise, if you just want to have the account preserved, you can stop posting.
If I stop posting? I think there is a possibility of my account being banned base on the past post I read the user stop posting for years and so banned account. But maybe there was something else, just to be sure so I ask a question here.
You are probably thinking about the hack which occurred in 2015. Accounts which didn't log in after that hack have been locked. They just need to sign a message from an old address and the account will be unlocked by a mod.
Your account will not be banned for just being idle. If you have infringed any other rules then you might be banned because of them, but not for being idle. You could stop posting now and come back in a year and your account will not be banned.
