Many, many more times than I care to admit.
Until the reason for some of this behavior hit home to me, I too would think of taking revenge on my fellow pax. But I see now that few people probably choose to grab your seat back simply to aggravate us. It's very difficult to determine by physical appearance why someone may need to grab a seat back. Could be a balance problem, could be a knee or other joint problem, could be vertigo. Or it could be a much worse physical/mental problem as has been outlined here.
I've become much more mellow as the years go by and these things no longer aggravate me. I just shrug this behavior off nowadays and say a silent thanks that I'm still able to rise out of my seat without help.
