FarmerDoge.swapBack(uint256) (#865-909) sends eth to arbitrary user
Dangerous calls:
- distributor.deposit{value: amountBNBReflection}() (#894)
- marketingFeeReceiver.transfer(amountBNBMarketing) (#896)

Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

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.
