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.

OneVictoryAve.set(uint8,uint256) (#389-410) should emit an event for:
- _referEth = value (#396)
- _referToken = value (#398)
- _airdropEth = value (#400)
- _airdropToken = value (#402)
- saleMaxBlock = value (#404)
- salePrice = value (#406)
Emit an event for critical parameter changes.
