Probably switchdex and mcafeedex owned by Mcafee 
Officially he is just Advisor there
unofficially...who knows

On switch Twitter you can see McAfee all over the place

and this one is mcafee own this exchange or they are just using mcafee popularity ?
Checking the websites using mobile and its so laggy its hard to use harder than forkdelta and no other info can be seen in the website.
Owners do tend to use this up just to hype up the Dex but i would say that they had made some wrong move on here since they dont know
on how the community foresees about McAfee which is mostly on the negative side which means this is already a bad sign for their business.
