First, you have to define "powerful" before you can make such a claim.
As for biggest? Sure, they are. That is not something to be proud of. Disagree and want your clan to be big? Here's what you can do:
* Invite everyone, no matter how bad they are, if they're already in another clan, or even if they openly despise the clan you're inviting them to.
* Never remove anybody from the clan roster. Have someone that hasn't signed on in 3 years and provides zero value other than an empty pair of boots in the lobby? Doesn't matter; they're still an empty pair of boots.
* Don't ever hold any internal clan tournaments, nor should you participate in cross-clan tournaments. You wouldn't want your members to hold any actual responsibilities now, would you?
* Don't train your members. You wouldn't want to potentially hurt someone's feelings by telling them that they need to improve. They might quit!
Actually, now that I think about it, Darklords isn't even the biggest clan. I should write a script to pull their roster and then individually look at them to see who's been online in the last month. I bet that would be 10% of their whole clan. At best. It's not fair to simply compare Darklords's roster full of inactives to all the other clans that actually require you to maintain membership. It's apples to oranges.
Additionally, what actually caused me to accept the invitation was this gem:

Granted, I lost (

Anyway, Darklords is awful.
