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.

Combination 2: Unchecked transfer + 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 ticker ($HAVEN) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
