Widely used tokens as Safemoon and Shiba Inu have reflection token mechanics, in which a percentage of the transaction gets reflected to other addresses. Because this protocol doesn't check for balanceOf()
after the transfer, this can lead to a false poolBalance
value, which disrupts the pool soundness.

state variable updates, corrupting all the other state variables which depend on this one.
Manual review.
Check the balanceOf()
