Nothing is worse than joining a guild that has instant join as a new player or on a new server and finding out afterwards the guild is dead or the guild leader as made a new main and a new guild or is in a new guild and now you have to take a leavers penalty.
There should be a system in the guild finder that guilds with less than 5 active members a day don’t show up when searching. New guilds will have to advertise in the channels for members and big guilds will have to constantly make sure their members are active.
