But in actuality, a matter of this seriousness should be brought to the attention of the venue management. Often the reason given for the post is to warn other players. And in this forum we do not allow identifying information (whether images, names or descriptions) to be posted.
In both types of posts, we usually have the person making the serious allegation using a screen name rather than real name (and in this case a brand new account) we only get one side of the story and the accused party may or may not even be aware of this forum. These types of posts are similar to ones where a player at a venue posts about someone not paying back a debt.
I deleted the posts related to an alleged collusion situation that included images of the alleged players involved, and some names.
