Is there a way to make messages blocked as bad content releaseable?
Hi
Is there a way to make messages blocked as bad content quarantined and releaseable ? Great also to send the notification to user that he has a blocked message.

Unable to release some blocked messages
Hi
Messages blocked as a "bad content" can't be released. Seems they are not stored. Where to find these settings? Would be great to notify user about blocked message by a content and store it. Please help.
