MetaverseNetwork.swapETHForTokensToHere(uint256) (#929-944) sends eth to arbitrary user
Dangerous calls:

MetaverseNetwork.addLiquidity(uint256,uint256) (#946-959) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#951-958)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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.

Contract ownership is not renounced (belongs to a wallet)
