Please post Skills that have been rejected by Amazon here.
Even when complying with Amazons stated content guidelines, Amazon reserves the right to reject Skills, "not all skills will be made available on Amazon Echo".
This ambiguity cast uncertainty for developers in: 1. Deciding to invest time and resources in developing custome skills for personal projects. 2. Entering into a contract to develope a skill for a client.
Perhaps, creating a collection of rejected skills can help fellow developers and business in making the determination if proceeding in skill development is worth the risk.
Not intended to be negative.
