TINDER.addLiquidity(uint256,uint256) (TINDER.sol#428-443) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (TINDER.sol#434-441)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

TINDERDividendTracker.getAccount(address) (TINDER.sol#517-560) uses timestamp for comparisons
Dangerous comparisons:
- nextClaimTime > block.timestamp (TINDER.sol#557-559)
TINDERDividendTracker.canAutoClaim(uint256) (TINDER.sol#581-587) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (TINDER.sol#582)
- block.timestamp.sub(lastClaimTime) >= claimWait (TINDER.sol#586)
Avoid relying on block.timestamp.
