This is what I would call it: 
Manure spreading. Lots of old rehashed excrement, nothing new really, no facts, lots of rehashed charges that dont stick and have never been prosecuted. Lots being flung for smell and entertainment and to see what sticks. When they post enough, the Washington Times, the Compost, NYSlimes, AP and Reuters will pick up the story and rehash it again. This has already happened from previous threads.
Wont make a whit of difference to the MMDC. Apparently the negative posters do not trust the IRS and AZ Attorney General, the Cochise County Sherriff's department, the Cochise County tax assessors or any other law enforcement to do their job. So they are flinging manure.
Flying manure has such a nice smell and is entertaining to all these folks. Especially if they have a politically motivated grudge not founded in reality.
