The crash was really bad for general market confidence, I'm sure even the most fervent fan of FI will acknowledge that. It's good that FI have taken some measures to address the situation. It's hardly a gimmick to close a market, actual stock exchanges do this!!!
As someone who perused the forum for a good while before signing up to FI, I would suggest that any newer/prospective traders consider how balanced some users on this forum are and whether there are other agendas at play. (And as with any online discourse, it's important to adopt a critical eye.)
