Characters auction are selling characters, gold and gear for Twinstar points. It's P2W and there is no way around that.
I'm not even going to explain how character auctions won't affect you in any way, form or shape. I'm tired of hearing this nonsense.
See, that's one of the things I like about Kronos : they're pragmatic and realistic. They adapt to the situation instead of sticking to the very end of the ''Blizzlike'' spectrum. If CAs are going to happen no matter what we do via the black market, what do we lose by not making some money out of it? Hosting a server costs money. And before someone replies ''exactly kronos admins are corrupt they want to turn this into a business and make personal money for them not the server'' : so what? Honestly, if our hosts can make a good living out of Kronos, GREAT. They'll be even more invested in the server and have the means to hire more people.
I usually compare it to the case of low lvl BG queuing, as both are an example of adapability and pragmatism (even though Kronos still hasn't given a definite answer). Sure the vanilla Purists with a capital P complain, but in the end, we have to think according to concrete consequences. This is not retail with multiple servers, each with thousands of people, linked in BG groups. This is a medium sized private server, and without innkeeper queuing, there won't be any BG 10-59. Ever.
