In this case I think it is because of a poorly written app. Sesef did an optimized version of several of their apps and they ran 500 times faster. Originally the admin was recommending it on the main page and giving the link to it.

Unfortunately, the admin doesn't know enough to fix a minor problem of validation! If someone is running as anonymous platform and someone else is running the stock app it will show as an invalid result. 2 wingmen running the app_info validates fine or 2 running the stock app validates fine but a mix doesn't work!

He also had to put out a "challenge" for someone to improve on one of his applications.

The dude running the project is in way over his head!!!!!!!!!!!!!!!!!!!!!!
