CupidFloki.addLiquidity(uint256,uint256) (#2015-2028) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,deadAddress,block.timestamp) (#2020-2027)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

TokenDividendTracker.getAccount(address) (#2182-2229) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (#2226-2228)
TokenDividendTracker.canAutoClaim(uint256) (#2263-2269) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#2264)
- block.timestamp.sub(lastClaimTime) >= claimWait (#2268)
Avoid relying on block.timestamp.
