I wish there was, but there isn't. I did a simple database query in regards to Kyle's question (posed to me in a past thread) -- and the number of gagged accounts was 93 -- the latest becoming #94.
Most of the accounts that have been gagged have nothing to do with Miles City itself -- typically, they are spammers, who actually bother to sign up and post some type of spam (why they go through the effort, I don't know) -- and they end up being silently gagged.
Realistically, there are probably no more than a dozen or two people related to Miles City that have been gagged, and in some cases, especially from the earlier days, a person would use multiple accounts -- thus adding to the number which became 93, and is now standing at 94.
