SMTP.swapETHForTokensAndBurn(uint256) (#906-921) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadAddress,block.timestamp.add(300)) (#913-918)
SMTP.swapETHForTokensToHere(uint256) (#923-938) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,address(this),block.timestamp.add(300)) (#930-935)
SMTP.addLiquidity(uint256,uint256) (#940-953) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#945-952)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

SMTP._transfer(address,address,uint256) (#718-862) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + uint256(keccak256(bytes)(abi.encodePacked(block.timestamp,block.difficulty))) % (buyBackSellLimit - _bBSLimitMin + 1) (#795)"
Do not use block.timestamp, now or blockhash as a source of randomness

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.

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.
