I'm having same issue. I cannot get Scirra Arcade to accept one of my titles.
"Your game appears to use plugins/behaviors not allowed!"
I have gutted the game, removed all the plugins, deleted the output folder, etc. There very well may be a behavior of plugin left but clicking on each object one at a time and bouncing against the list is just a waste of time. How about listing the detected plugins and behaviors not allowed to better help us find them?
I've got it up on Google, clay.IO and My Site but for the life of me I cannot get it uploaded to scirra!
So anyone know of a faster way for me to detect NON-Scirra approved Plugins/Behaviors?
