" I was told by someone still working there HR declared unfriending a fellow employee was considered bullying."

Would not go into detail but in my past I've encountered some peculiar things that HR was trying to impose on employees. I just told them to sod off and keep me away from their kindergarten. The HR person I talked to was sort of shocked but they did leave me alone. No actions were taken. They just asked me not to promote my view among other employees which I was not interested with anyways.
