The father of a pupil at a Black Country school who claims his son has been repeatedly bullied has set up a website airing his concerns.
Robin Lowe says he will not back down
Sandwell Council has threatened to take Robin Lowe, from Oldbury, to court unless he takes down the site.
He set it up a week ago claiming staff at Tividale High School and Community College are not disciplining pupils.
Mr Lowe, who has refused to remove the site, alleges his son has been attacked six times at the school.
The council has given Mr Lowe until 1600 GMT on Wednesday to remove the site or it says it will take out an injunction against him.
He has offered to remove the names of teachers, but says he is keeping the allegations on the site.
They include claims that children are being kept behind for detention without the necessary 24 hours' notice being given to parents.
Mr Lowe also claims that pupils' hair is being set alight at the school.
He said: "I will defend the legal action."
Councillor Ian Jones, cabinet member for education at the council, denied the allegations branding them "inaccurate". He added recent publicity is damaging the school.
The school hit the headlines last week after two teenage girls were allegedly caught smoking heroin in the school toilets.
Mr Jones told the BBC there had been "misinformation" about the girls, and they were actually suspended over an allegation of theft.
In a statement, Mr Jones said: "We regret having to take this course of action.
"We very much hope that the situation can be resolved by the simple withdrawal of the website."
