fBUSD [FomoBUSD] Token

FomoBUSD.swapBack(uint256) (#1076-1122) sends eth to arbitrary user
Dangerous calls:
- _marketingWallet.transfer(amountBNBMarketing) (#1105)
- reflector.load{value: amountBNBReflection}() (#1121)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

FomoBUSD.swapBack(uint256) (#1076-1122) ignores return value by dexRouter.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,burnAddress,block.timestamp) (#1108-1115)
Ensure that all the return values of the function calls are used.
