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.

LiberaToken._checkAndPayBiggestBuyer(uint256) (#854-870) uses a dangerous strict equality:
- _currentPeriod > 1 && biggestBuyerAmount[_prevPeriod] > 0 && biggestBuyerPaid[_prevPeriod] == 0 (#857-859)
Don't use strict equality to determine if an account has enough Ether or tokens.

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

LiberaToken._isContract(address) (#665-669) uses assembly
- INLINE ASM (#667)
Do not use evm assembly.

Low level call in LiberaToken.retrieveBNB() (#961-966):
- (success) = address(msg.sender).call{value: amount}() (#964)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

LiberaToken._checkAndPayBiggestBuyer(uint256) (#854-870) uses timestamp for comparisons
Dangerous comparisons:

LiberaToken._accuTaxSystem(uint256,bool) (#904-934) uses timestamp for comparisons
Dangerous comparisons:

Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
