Question

A fraudulent contractor sold apartments with many defects.
I brought a certified expert to the court, who inspected the apartment and wrote a report.
Now I have gone to civil court (on the instruction of the religious court, because the contractor made a mockery of the religious court) with a claim for a substantial amount.
 
The contractor is willing to settle for some amount in order not to reach a ruling in court.
His main concern is that the whole neighborhood will learn from what I did and sue him for his wrongdoing. He does not feel like paying for the wrongs he has done.
 
Therefore he wants to reach a quiet arrangement.
But he has one condition: that the whole matter not be publicized. I want 100,000 NIS for that clause.
And without it, on the contrary, I will make sure to inform anyone who has the patience to listen that I sued and succeeded, and, God willing, I will even send the documents by email in order to teach everyone how to sue the fraudster.
 
All in all, a great commandment of returning a lost item has come my way.
 
My question:
Is it permitted / appropriate to accept 100,000 NIS in order to refrain from the commandment of returning a lost item?
 
It should be noted that we are a community settlement; everyone knows everyone, and the contractor also lives in the settlement.
If I publicize what happened, it will give legitimacy to many others to sue the thief, because right now it is perceived as something unfriendly and inappropriate.
