Blackmailing, defamation and extortion by land mafias.

Some infamous local land grabbers are sending us whatsapp messages and calls and are threatning to defame us by making Posters with our pictures and defaming slogans and taking out possessions and also circulate such posters in social media and make false stories and use some local media houses owned by them to further promote these things in city. They want us to sell our land against an agreement which they have not even paid for (rear brief histrory below). They have done similar defamation activities with other people in city earlier to pressurize them to do things they want. Can we file a blackmail/extortion/ defamation case. As proof we have received whatsapp messages from the main culprit showing sample of posters and voice note threatening and abusing us. How can we prevent such defamation activities. Brief History: In 1996 we purchased some Land (from 3 sellers under 4 deeds) under our company name. For 13 years period 1996 to 2008, we peacefully conducted agriculture and farming activities. Due to business related issues the agricultural activities were stopped for sometime. In 2011 some local land Mafia manipulated one of original land sellers and forcefully tried to capture land with false documents. In 2019 Land Mafia forcefully and under pressure also made us sign an agreement to sell the land for 1/10 the market value. As per agreement the value to be paid was say Rs100 but they paid only Rs10 till today (paid online). In 2021 we won the civil suit after 10 year long legal battle and Hon'ble court passed the decree in our favour. Land Mafia Nexus threatened us with defamation through false cases and various other means. For payment they claim to have paid online Rs 10 and balance cash which is not true.
