AOC Wiki stipulates that Alts on the same account can join different guilds. Intrigue, espionage and intelligence gathering is a legitimate aspect of the game.
In other words, and hypothetically, if I intend on having a small guild, an uber guild can take 30 alts and become members. Then that guild is subject to a hijack, member vacuum, or take over during elections of those 30 alts? My issue is that if evasion is such a big deal on Discord and Forums, why foist this same burden on guild leaders of small guilds? And how can one tell IF the appropriate primary accounts are dedicated to a guild and not alts to be recognized as a guild? This makes me pause and may dissuade others from a) forming a small guild and b) having elections. The risks are too great to invest in hard work, spend money on kickstarter uber packages, with no modicum of risk mitigation. I hope the designers visit this legitimate concern. A spy is one thing, but a coordinated and simple take-over is another. What measures are in place to give the guild founders of a small guild a reasonable comfort level in preventing a devastating sabotage of a raid (where members quit) or a corporate take-over? If the answer is some obtuse non answer like it's risk and reward I say heck no. It's a lot harder to break or take over a big guild from the outside. For your consideration.
