Residents harassing association members! Help!

In my luxury society couple of residents with vested interest have been harassing the board since sometime now. With false accusations, constant threats of police complain and general nuisance in social media. We got this association after much difficulty after nobody volunteered. Now I feel very sad for the association members for facing such constant mud slinging. Now these guys have even floated a google form asking for a GBM ([https://forms.gle/bPqyGf7tct6Pmv7B9](https://forms.gle/bPqyGf7tct6Pmv7B9)). How should regular, peace loving residents like us handle these nuisance makers? Please help!
