But it's irresponsible to permit someone with sour grapes over a week- late delivery to post a thread claiming a company's demise. This can have implications for the business in terms of credit worthiness, suppliers demanding early payment etc
As for chasing down rumours, it should be apparent from the OP whether someone is discussing a genuine case of a company closing it's doors, making staff redundant etc, or just whining about what they feel to be bad service.
Any self respecting website does not want to be a source of misfounded rumours, even malicious rumours like we've seen this week.
Personally i feel that if somone posts an intentionally misleading thread claiming the demise of a healthy company they should have their thread- starting priveliges removed
