AddonMessage Flooding/Mass Disconnects?

[Roeshambo]

I do use ChatThrottleLib, which is why the disconnects had me a bit confused. It's not the frequency that is causing the disconnects. It's been tested at length in medium size guilds with no issues. It's not until a large guild uses it where disconnects suddenly become a problem. And it's not a handful of people here and there go offline. Every single player in the guild using the addon gets DCd. Simultaneously. At least, that's how it's been explained to me by those that experienced it.
