Inspiration4.swapExactETHForTokens(uint256,address) (#1584-1586) sends eth to arbitrary user
Dangerous calls:
- transferHelper.buy{value: amountIn}(tokenAddress) (#1585)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Inspiration4._transfer(address,address,uint256) (#1455-1524) uses a dangerous strict equality:
- launchedAt == 0 && _from == owner() && automatedMarketMakerPairs[_to] (#1461)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

SafeMathInt.mul(int256,int256) (#530-537) is never used and should be removed
Remove unused functions.

Pragma version^0.6.2 (#3) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Inspiration4._transfer(address,address,uint256).lastProcessedIndex (#1520) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Inspiration4.swapAndLiquify(uint256) (#1563-1570) ignores return value by uniswapV2Router.addLiquidityETH{value: halfForEth}(address(this),tokensOut,0,0,address(0),block.timestamp) (#1569)
Ensure that all the return values of the function calls are used.

DividendPayingToken.accumulativeDividendOf(address)._owner (#1091) shadows:
- Ownable._owner (#329) (state variable)
Rename the local variables that shadow another component.

Inspiration4.setMaxWalletAmount(uint256) (#1371-1374) should emit an event for:
- _maxWalletAmount = amount (#1373)
Emit an event for critical parameter changes.

Inspiration4.updateUniswapV2Router(address)._uniswapV2Pair (#1289-1290) lacks a zero-check on :
- uniswapV2Pair = _uniswapV2Pair (#1291)
Check that the address is not zero.

Variable 'Inspiration4._transfer(address,address,uint256).lastProcessedIndex (#1520)' in Inspiration4._transfer(address,address,uint256) (#1455-1524) potentially used before declaration: ProcessedDividendTracker(iterations,claims,lastProcessedIndex,true,gas,tx.origin) (#1521)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

Inspiration4DividendTracker.canAutoClaim(uint256) (#1693-1699) uses timestamp for comparisons
Dangerous comparisons:
- lastClaimTime > block.timestamp (#1694)
- block.timestamp.sub(lastClaimTime) >= claimWait (#1698)
Avoid relying on block.timestamp.

Variable DividendPayingToken._withdrawDividendOfUser(address)._withdrawableDividend (#1046) is too similar to Inspiration4DividendTracker.getAccount(address).withdrawableDividends (#1654)
Prevent variables from having similar names.

Use: Ether suffix, Time suffix, or The scientific notation

Inspiration4DividendTracker.minimumTokenBalanceForDividends (#1606) should be constant
Add the constant attributes to state variables that never change.
