MPLAY [MetaPlay] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract creator or owner is blacklisted for past scams

Contract ownership is not renounced (belongs to a wallet)

MetaPlay.setFeePercentage(uint8) (#293-298) contains a tautology or contradiction:
- require(bool,string)(feePercentage_ >= 0,MetaPlay: transaction fee percentage equals 0) (#295)
Fix the incorrect comparison by changing the value type or the comparison.
