DORINU._transfer(address,address,uint256) (#593-640) uses a dangerous strict equality:
- block.timestamp == launchTime (#610)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

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.

isRemovedSniper(address) should be declared external:
- DORINU.isRemovedSniper(address) (#860-862)
Use the external attribute for functions never called from the contract.

Ensure that all the return values of the function calls are used.

DORINU._previousLiquidityFee (#419) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.7 is not recommended for deployment
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.
