Name similar to Spotify for extension request

[LeoDeng]

Regarding Spotify's design guidelines:

• It cannot begin with “Spot” or be similar to “Spotify” in sound or spelling.

I want to learn to what extent a name can be similar to Spotify. My domain was rejected because it used the word "Spotify" but I also use another service that has the word "Spotify" in their domain. I'm not sure if this is because they were approved before this rule.

Also with the popular service "Receiptify", I'm wondering if adding "ify" to the end of your name is fair play. I want to learn the extent I can go before waiting another 2 months for my extension request.

So, which name did you use?

Spotify Sifter

That has clearly the full Spotify name, and that is prohibited.
