daoMetaverse._transfer(address,address,uint256) (#774-813) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.

Pragma version^0.8.11 (#1) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 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.

Attempt to swap token was unsuccessful. For some reason it is untradeable. If token is not in presale stage and is not traded outside PancakeSwap, then it's a scam

Additional information: link

Average 30d PancakeSwap volume is low.

Average 30d number of PancakeSwap swaps is low.

Average PancakeSwap trading volume, liqudity, number of swaps are low. Token seems to be inactive.

Token is deployed only at one blockchain
