I know i will be getting highly downvoted for writing this , but i will still write this up because i really wanna put forward my point . I know sus is getting tremendous support for his anime blogs but i think the way sus blogs are getting upvoted its replacing some more important blogs from the recent action post like blogs telling about some other platform contest announcements or some Cf users sharing there approaches for a problem or explaining a tough topic . I therefore request everyone to stop this as some other blogs are getting affected a lot which are really useful (atleast for me who have started cp just now ). Thanks for reading this up and have fun doing CP.
