Human Factors
The sector to the south of me was coming out of the hold for ZZZ. ZZZ1 sector pointed out an aircraft in a right hand turn out of the holding stack back on course at FL370. I accepted the point out via automated means. No further coordination was accomplished and ZZZ1 sector descended the aircraft to FL310 while still in my airspace. No further call was made. This is a growing problem and has been ever since automated point outs where introduced. Controller(s) take accepting an automated pointout as blanket control.I've filed numerous reports on this issue and still nothing has been done. The definition of a pointout has not changed. If I accept an automated point out; I'm accepting what the data block and route of flight is showing. I am not giving away control of that plane. Further education or briefings need to take place before an accident occurs. This happens on a daily basis.
ZOB ARTCC Controller reported a violation of a point out; when another Controller descended an aircraft without permission.
