I assure you, David and this other person Jeff are two completely different people. Aside from the stubble on the profile photo of each person, and having similar interests in WordPress, that's about where the similary ends. You really shouldn't make false accussations based on a photos you have seen on the internet. If someone wants to mistake me for Sophia Vergara though, feel free ;)
The only reason why Jeff's website shows up in a search of "AppThemes" is because that URL contains the text "App" and "Themes"
