Suicide Stopper

High impact posters appeared on the platform of subway Sannomiya Station. No photos or pictures, just simply letters. There are several patterns, but the all the messages are very negative, like complains of each generation - young unemployment, middle age workaholic, bored retirement, etc. I heard the posters are for suicide stopper. Do beleaguered People stop suicide reading these? I guess people who don't have any trouble must be depressed more if they look at them every day...
