Token is flagged by TokenSniffer due to presence of exploit in contract code


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)

MetaWarToken._decimals (#338) should be constant
MetaWarToken._name (#336) should be constant
MetaWarToken._symbol (#337) should be constant
Add the constant attributes to state variables that never change.
