Agreed.
Reviews cost nothing, scams bootstrap poor quality amazon products, and low quality restaurants.
A more useful heuristic:
-time of operation (e.g. 10 days, 100 days etc)
-proof of prior rugpull (if any)
-people in your WOT who “vouch” for a mint
-mint owner or admin
Latter two are unlikely public info, and likely not practical or useful
