Massclaim

It is common in Theme Games for the Roles to be named based on some theme, such as characters from homestarrunner.com, trees, or fictional space colonists. Because of this, the Town may be able to theoretically guess which Role Claims and/or Name Claims are real and which are false based on how well they fit into the theme, not on the player's actual actions during the game. Reasons for 'catching' someone in a false claim range from obvious reasons like "It's Zarquon, not Zarquar" to more esoteric ones like "Would Rincewind really be a good guy?". This has given rise to a strategy called the Mass Roleclaim (or massclaim), in which everyone reveals their role and then those who are less plausible get lynched. This is considered by many to be a corruption of the game and a Breaking Strategy to boot.

As a result, many Game Moderators have added roles to their games that stretch plausibility in order to thwart such tactics. The players in Texas Mafia Returns got a nasty surprise when they discovered that one of the Pro-Town roles was a pirate! It is now considered poor form to create a game that can be immediately broken by massclaim.

Unthemed Open Setup games may also be vulnerable to Mass Roleclaim when too many players have unique roles. Since the number of each role is known, by having everyone claim their role, the town can swiftly narrow down which players must be lying. This can be far more valuable than whatever abilities the roles actually possess, so that it's not a deterrent that Mass Roleclaim allows Mafia to immediately learn everyone's identity.

Massclaim is also used as a last resort tactic for Towns in every kind of game, trading the anonymity of hidden power roles for hopes of catching scum in falseclaims or identifying Townies by their power roles.

Methods

As a general rule, Towns prefer for scum to claim early. A scum player near the end of the claim order can falseclaim more effectively with the knowledge of previous roles. For instance, if no Cop has claimed by the end of the claim sequence, a Mafioso can claim Cop with little fear of being counterclaimed.

Popcorn

Usually the players choose by consensus one of the scummier players to claim first. As each player claims, they declare the next person to claim.

Random

As its name implies, the claim order is determined randomly. This is done either with each player posting a dice tag as they claim, or by posting a randomized sequence and claiming in that order.
