I understand your frustration but please keep in mind that people mostly join these forums so that they can collaborate with others and also compare their own data with others.
Although I am a January applicant, I do frequently visit and often post in other areas of the forums like in the NOV-Dec applicants
http://www.canadavisa.com/canada-immigration-discussion-board/november-december-2015-cic-applicants-t385234.2220.html. These are very close to my own dates, and often times once someone reports that December applicants are getting some notifications, the January and February applicants can watch their own applications for those notifications. I see a lot of people on that thread from September and October.
Your concern is that May applicants are in this thread, when they don't 'belong' here. They are watching the activity of the March applicants as they are only 2 months ahead and they will be making preparations accordingly. This is a common occurrence across all threads.
Once someone from March reports that they received their MR, May applicants will naturally start preparing themselves for MR too.
I think things will not change with this anytime soon and that's fine by me.
If you don't like it, you can simply leave. It's not like somebody is forcing you to stay.
