First of all, let me remind you: One can go to any wifi-free Tim Hortons, log in to the forum, say anything they want and walk away. The whole process of tracing IP, requesting court order, matching identity and lastly throwing files to back of the line doesn't make anything better.
While I dont think it's appropriate to make a joke that way about CIC, I also don't think it will be as serious as you say. Instead of spending time on forums like this, CIC staff should focus on their works which they get paid to do. Secondly, if they do find something offensive and successfully convince the web owner to release the IP, then from the IP address in order to trace physical location of the people will require court order s(internet providers only release with court orders). Now come the question: what will be the ground for CIC to request court order? To chase behind the people who offend them? Do you think they have time and resource for such things? They must work 300% harder to clear the backlog. The more they delay, the more public will make fun of them.
In my opinion, the thing you are worried about is nearly impossible to happen. I am not sure if CIC staff does have time to stalk on people as you said. I hope they do. So they know how bad they look in public views. In fact, none of these discussions are national security threats. Talks like this one happen in any democracy. Nothing unusual. At least for me I have nothing to fear. But it's better to keep diplomatic tone just to respect everyone.
The process of "revenge" for public offences will require more efforts than just open the backlogged files, and work on them. All the online activities on forum, Facebook page will bring benefits, gradually, to improving processing time - because they make public aware of the situation and the government doesn't like that. Unless it is a security threat, there is none, absolutely zero, nothing CIC can do, to revenge individuals who express their opinions.
