Google removed today my app from play store... :( and I don't know why... They wrote to me few days ago that my app is violating some spam terms, I read them again and they were right. I posted links to my other apps in app description - my fault, I wasn't aware of it. I removed immediately those links from every app description. No good, they removed one app - TSF Holo Orange. I wrote to them about it but I'm not sure if it will help. I'm really sad how it was handled. Maybe I should think of different model of distributing my apps if Google plays like this in future.
