They haven't said or updated the steps that they will do to filter those scams or fraud ICO. Hard earned money is not easy to let go, so if you are being scammed by these it surely is heartbreaking.
Even though they didn't mention on their whitepaper on how to avoid or filter those scammer, i believe that Arizn has another way to filter it. Of course before they fund other busnisses or accept investors i am sure they will also conduct their own private invistigation.
Not just that, i am pretty sure that the team will not just investigate the project.
ARIZN will have their INVESTIGATION DEPARTMENT/TEAM for every ICO they will have for others.
they will not let their reputation be torn because of other project.
