PinkToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/dot/contracts/dot/PinkToken.sol#240-258) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/dot/contracts/dot/PinkToken.sol#250)
Don't use strict equality to determine if an account has enough Ether or tokens.

PinkToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/dot/contracts/dot/PinkToken.sol#106-147) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,PINK::delegateBySig: signature expired) (contracts/dot/contracts/dot/PinkToken.sol#145)
Avoid relying on block.timestamp.
