Going through the list of [recently migrated questions][1] (10k), some of these really need some editing or other moderation.

What you see quite often on those questions [are comments like][2]:

> - not seeing how this is a ServerFault question. – *ceejayoz* 1 hour ago	
> - Which forum should I move this to? StackOverflow? – *Mark Lutton* 1 hour ago	
> - It has even less to do with StackOverflow. – *ceejayoz* 41 mins ago

Now that the question is migrated, they don't serve any purpose and distract from the actual problem.

**Should I flag for moderator attention to have those deleted?**

If so, how should I do it? 

- A comment flag, specifying the "Other…" option, asking for comment cleanup?
- A normal flag on the question itself, with the same reason as above?
- A flag on each individual comment using the "Obsolete" flag reason?
