The afk system and the flaw that it has

Now obviously everyone knows that when you have a player who goes afk it's annoying since you and your teammates have to deal with the bs that is the enemy champions especially since some champions have bs abilities. But that's now what the discussion is. The real issue is how bad the afk system is. It punishes players based on how many games they have gone afk. Eventually you are put in LPQ which starts from waiting 5 minutes to 10m and finally 20m. The issue is how the afk system doesn't take into account the reason the person has gone afk. In my case i've gotten another 20m LPQ because like always my folk call me and tell me to do something and when i try to tell them that I'm busy and that i'll do it as soon as I'm done with a game they start to become stubborn and not caring that you are in a game and that there are other players who have to suffer from you being afk. Now i don't know if there is a way to be able to file that I've been set on a LPQ because of people that always tend to not understand you can't a pause an online game and you never will be able to and while i feel bad for my team who fights and gets killed while my champion sits at spawn like nothing was happening i also wish they considered that everyone has a reason to be afk. Wether it's because your internet went out, parents constantly bothering you to do something or else they'll take away the pc and etc... Now there is the possibility that people would take advantage of there being a way to get rid of your LPQ since many people go afk cuz they get salty or because they just wanna be a troll but still it takes into consideration of what is going on in the players life that might affect them no being able to play the game.
