a lot of companies have been involved in questionable activity

simply pointing at them is irrelevant

the reasons for ISX's shares being suspended are well understood (albeit ignored by most holders) - ongoing refusal to demonstrate an intention to comply with the listing rules, and ASIC litigation which questions the # of shares on issue
