Two things are involved
1. Either the exchange doesn't carry out any due deligence to ascertain if such projects are legit or
2. Their ieo fee is little to nothing
if the exchange was a top exchange they should attain their softcap at least
But it proved Most of coins/tokens hosted ieo on p2pb2b are scams
Yes I do not remember an IEO who walked on p2pb2b they make false statement
In my opinion is better to avoid IEO listed in this exchange
I don't know if someone really like this exchange but, But i don't like this exchange even from day one,
IEO ? i even don't join that bounty also which project starts ieo on p2pb2b
