ANON [Anonverse] Token

AnonverseToken._safeTransferETH(address,uint256) (#977-980) sends eth to arbitrary user
Dangerous calls:
- (success) = to.call{gas: 2300,value: value}() (#978)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

AnonverseToken.transferBack(address,address,uint256) (#875-882) ignores return value by IERC20(tokenAddress).transfer(to,amount) (#880)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

Contract ownership is not renounced (belongs to a wallet)

AnonverseToken.getTokenPrices() (#1030-1043) performs a multiplication on the result of a division:
-priceWBNB = WBNBBalanceAtANONPair * 1e18 / ANONBalanceAtANONPair (#1037)
-priceUSDT = priceWBNB * USDTBalanceAtPair / WBNBBalanceAtPair (#1042)
Consider ordering multiplication before division.
