I'm a little stuck... Click here to teach me more about this clue!

'furious screed did it it ruined their good name' is the definition.
I can't judge whether this definition defines the answer.

'furious screed did it' is the wordplay.
'furious' indicates anagramming the letters (I've seen this in other clues).
'screed'+'did'+'it'='screeddidit'
'screeddidit' with letters rearranged gives 'DISCREDITED'.

Can you help me to learn more?

(Other definitions for discredited that I've seen before include "Shown to be false" , "One treating dirty garments" .)

I've seen this clue in The Irish Times.
