Is your agenda:
a) a scorched earth, drain the swamp, fight to the death clean up corruption. (aka, HH v2)
b) recognize that we can't change the past (your mantra?), therefore there is no need to blame or bash anyone - including M&M.
Rather run a campaign to raise massive awareness about the scope of the town's problems, and by this apply pressure on the governing bodies to cease and desist from further development.
If it a), you are going to fail and lose a lot..
If b)- you are holdings your nose and working within the current system to affect change anyway..
If so, go to the vaad, go get rabbinic backing. Etc
If you were totally above board and clean, (no negativity), you could even reach out to the Yated for publicity... (Shmuel berinboum should be a big ally imho) etc.
