Don, I'm referring to the UAE cyber crimes law, if you are found in breach of it then yes you can go to jail. (Spreading rumor, false information, or any kind of posting that can cause damage to reputation, commercial interest yada yada)
Don't forget that we all agreed to abide by the ERM which includes keeping confidential company info just that. Half the posts on pprune are technically in breach of it, just lucky for us they seem to not have the time to follow up on most of it (although they have been known to pull people into the office to give them a rap across the knuckles for posting in here, and that is just for chitchat)
if someone were to post up confidential safety info here, whether true or not, and they can identify that person, I personally wouldn't be worrying about whether jail time is a rumor or not. I'd be worrying about how to get myself out of dodge.
There is no 'whistleblower' legislation in the UAE. That's not galley talk, that is fact.
