I cannot see how the army would be of any use in the eventuality of the major expose. There was this other person with huge following among scepticals of everything (sorry I don't remember the name exactly) who got a huge fine recently. I don't believe justice would look the other way, if anything, it may be attracting scrutiny with attention.
Money, PR, astroturfed protests, moral support. This can be true even for people in prison in legally non-controversial cases of murder. Quite a few serial/mass killers have fan clubs. I don't mean true crime nerds who happen to be interested in a particular villain, I mean literal fan clubs that write regularly, put money in the prison commissary account, recruit other fans and so on.
playing devil's advocate here for a moment : having that 'army' would eventually be useful if say you knew an exposé was on the way because they may become an exploitable market once the mainstream throws you to the wayside over the allegations.
the 'army' can be fed some insider-flavored tripe : "THEY are using this to get me.", "Of course this comes out when i'm trying to expose the truth", etc etc.
So, in other words, the 'army' isn't directly useful against the allegations necessarily, but as a fall cushion once those allegations and possible criminal charges land and alienate the rest of the 'normal' public from you.
Alex Jones/Sandy Hook comes to mind. In some warped sense, the criminal allegations and justice pursuit towards Alex Jones with regards to his comments regarding the Sandy Hook shootings cemented him as a 'victim of the system' for a lot of his adherents; much to the dismay of everyone else.
