Actually, apart from <PERSON>, no one else seemed to be getting detention from <PERSON> (atleast until she became Headmistress). As mentioned by <PERSON> <PERSON> refused to complain about her even though he was urged to do so by <PERSON>, seen in Harry Potter and the Order of the Phoenix, Chapter 13: Detention with Dolores
“Yeah, so do — <PERSON>, what’s that on the back of your hand?” <PERSON>, who had just scratched his nose with his free right hand, tried to hide it, but had as much success as <PERSON> with his Cleansweep.
“It’s just a cut — it’s nothing — it’s —” But <PERSON> had grabbed <PERSON>’s fore arm and pulled the back of <PERSON>’s hand up level with his eyes. There was a pause, during which he stared at the words carved into the skin, then he released <PERSON>, looking sick.
“I thought you said she was giving you lines?”
<PERSON> hesitated, but after all, <PERSON> had been honest with him, so he told <PERSON> the truth about the hours he had been spending in <PERSON>’s office.
“The old hag!” <PERSON> said in a revolted whisper as they came to a halt in front of the Fat Lady, who was dozing peacefully with her head against her frame. 573
“She’s sick! Go to <PERSON>, say something!”
“No,” said <PERSON> at once. “I’m not giving her the satisfaction of knowing she’s got to me.”
“Got to you? You can’t let her get away with this!”
“I don’t know how much power <PERSON>’s got over her,” said <PERSON>.
“<PERSON>, then, tell <PERSON>!”
“No,” said <PERSON> flatly.
“Why not?”
“He’s got enough on his mind,” said <PERSON>, but that was not the true reason. He was not going to go to <PERSON> for help when <PERSON> had not spoken to him once since last June.
These are the reasons <PERSON> didn't mention it to anyone. The only time the book mentions anyone else getting this sort of similar detention is <PERSON>, and by then <PERSON> (though not Headmistress yet), could only be superceded by <PERSON> and even upon his intervention might have just brought in another Educational Decree that stated she was in complete control of all detentions.
To be fair, once <PERSON> was gone and she became Headmistress, the students were much more rebellious and she seemed to have lesser control than ever. 417
