SAO [Sword Art Online] Token

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

Ownable.unlock() (#457-462) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now > _lockTime,Contract is locked until 7 days) (#459)
Avoid relying on block.timestamp.

SwordArtOnline._rTotal (#497) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
SwordArtOnline._taxFee (#512) is set pre-construction with a non-constant function or state variable:
- _buyTaxFee
SwordArtOnline._previousTaxFee (#513) is set pre-construction with a non-constant function or state variable:
