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

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

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.
