Is that really as widespread as you say? I looked at the last few hours of the six most popular chat rooms and control-f'ed for "cv-pls" on all of them, and found a grand total of ONE hit: http://stackoverflow.com/questions/28568303/python-3-object-...
The question was closed because the asker himself answered it apologizing for posting it, the problem being something completely unrelated to the code he had pasted. Everybody agreed.
At least looking through sopython, with the exception of today, it's an average of 1 every ~20 minutes during "peak" hours. There are deliberately fewer today, due to the room's discussion of them this morning, but have a look at: http://chat.stackoverflow.com/search?q=[cv-pls]&Room=6&sort=... as an example (particular days before today).
The majority of those are questions that should be closed.
It's just that a lot of wheat gets thrown out along with the chaff.

I don't think it happens that frequently.
