Unfortunately, their "verified" and witnessed sigs both get yellow labels now.
Some say this gives them added exposure they wouldn't get otherwise, like if they were on a convention wall display mixed with yellow witnessed slabs. To me this feels the same as using "Not CGC" on eBay as it forces people to look at something they don't even want to consider, only in this case it would be "Not Witnessed".
When they used a red label, you knew what you were looking at from a distance- It was "verified." If that wasn't your thing you could quickly move on to the witnessed. Of course, this is really only a problem at shows, or for people who don't read listing details.
Anyway, both get yellow now
