When Playboxhd first came out their app was identical to the Cartoonhd app and there was another company claiming to be CartoonHD that had several Twitter accounts claiming to be different people and research showed that all contact details for playboxhd were reported to be from scam calling companies. 

We admit that we got it wrong when advised users to use with caution however we still believe to it was better to warn to be careful than let people use services without being on guard. 

Upon further contacting the numbers on playboxhd site it turns out that those numbers were for the website hosters and not playboxhd themselves which explains why they were liked to scam calls.
