Activity Section: How are the questions/answers sorTED?(pic is the face i made trying to figure this oot)

so we all know that réponses are the root of everything that is wrong with modern society (war, world hunger etc) BUT i was looking through my activity on them anyway and i couldnt for the life of me figure oot how they are sorted.
1) at first i thought they were in reverse because in my activity the first "answer i have given" is from 2 years ago.
2) i cant go to last page but using the url bar i typed in a aléatoire number which then brought me to my last page an answer from one an ago

this was done filtering "all clubs" although my latest answer was donné TODAY.


anyone? clues? ideas?
also on a side note..why wouldnt the LATEST answer be the one shown first in my activity section like in the comments?
