I'm editing my save file since 2017.. I've never got banned. And I've got reported 1 time because i killed a SWF Team with Nurse so fast they called me an wallhacker..
just be careful with the values (date times etc) and dont give yourself 9999999 items... also my account is not private, and the archievments are legit.. AND NEVER HACK LEGACY, even if your legacy is legit NEVER WEAR IT ON AN EDITED PROFILE. If you get reported for hacked legacy, devs will watch your savefile 100%.
