Why too many AMAs nowadays , almost half of the recent actions is occupied by this trend.

Hello Codeforces!
I hope you would have enjoyed the recent contest Div.4 as its always easy for most of the community.
But there can be some problems,
And I would not like to waste your time on reading unnecessary things , so let me just start the real blog...
Today's contest's E problem 1829E - Озера was very much similar to this (or rather the same)
Actually the problem statements were different (but there was water in both ;) ) but the solution was exactly the same if you copy code of one problem and submit it into another it would get accepted but of course you would have to add/remove the code of multiple test cases.
Now what I want to say that this could be a coincidence , I don't want to blame any of the writers or testers but this thing needs be looked out. Because these kind of things really effects the contest results and hard work of many.
And the thing left about that the contest would be rated or unrated is simply the decision of MikeMirzayanov and the contest creators.
