Those of you doomed to roam the O chat for all eternity:
Start gathering information about newly forming guilds. Namely, prominent members who join or mention support of such guilds, and similar information.
While it is unreasonable to hold other towns to Malum's standards, we will make some assumptions based on the available information. That is, if multiple prominent members of a neutral/good aligned town join or pledge support to an evil or unethical cause, that town will be added to our list. As a reminder, per Malum standards, any citizen joining a NON-GOOD aligned guild will be expelled from Malum without warning or question. This extends to everyone within the town, whether we're best friends or not. This extends to myself - If I join or pledge support to such a cause, I forfeit ownership of Malum to my SIC.
In an ideal world, all towns would throw out their weak members like we will. Sadly, this is not the case, and mayors in such instances tend to turn a blind eye to the evil deeds of their citizens. Now is a grand opportunity to give a "purification through fire" speech, but I am more of a diplomat than a war leader.
