When was this? I remember them listing everything after they were in 2 exchanges. That's the only requirement i can remember them having back in time before Binance took it over. They are just not going to rank something with made up marketcap and 2 token holders, that's enough security to me. It would be insanely difficult to filter everything "legit" as people are trading tokens that are not "legit" they would just move to coingecko or other marketcap indexers that list them.
