Autofill exacerbating the "trolls banning your pick when you got 'their' lane issue

So lots of people have a problem with autofill, right? It's not exactly my favorite part of league either but I see it's purpose.. Everyone was locking in top, mid and jungle leading to extreme wait times to start a game. I fear that autofill, however, hasn't solved the problem it has only created a different one.

Last night a friend and I tried to play a normal summoner's rift game for over half an hour before giving up and switching to ARAM. Our adventure in duo queue started with, shock of shocks, an autofilled support saying "switch top with me" which I of course declined having just been autofilled myself in a recent game earlier that day I figured "hey, it happens to everyone unless they play the occasional support game" which is also what i said to this support. Their response was "fine then I'm feeding". This being far from the first time I've encountered an upset troll during champ select I naturally changed the champ I had selected seeing their next move coming from a mile away, when their turn to ban came up they, quite predictably I might add, banned the new champ I had selected after which I re-selected my original choice. I laughed and politely asked the rest of our team to report the angry troll for griefing and proceeded to inform my supposed-teammate-turned-griefer that i would ask the same of the other team once the game began. This earned me a string of profanity from the now-defeated troll after which they dodged the queue.

The next few attempts were rife with dodges motivated by autofilled players unhappy with their designated positions, but thankfully only one who said they would troll and feed and whatever else they could muster as threats before they also dodged when the whole team agreed to report after the game. This is the point at which we decided ARAM would be less of a hassle. Which it obviously was.

Today is the same story, literally every game that I'm top I face an angry troll capslocking "TOP OR FEED" or some other such threat followed inevitably by said troll trying to ban my pick. This clearly outlines the problem, Autofill gives people the "right" (in their opinion) to ruin other people's games because theirs was "ruined" by a matchmaking mechanic.. now how about a solution?

I propose this as a means of stemming the flow of similar incidents; If you get autofilled and you dodge, you should suffer an increased time penalty before joining another game. Say an hour or so, maybe two, heck I would make it a 24 hour ban but sometimes accidents happen so that might be a little too harsh. this would, in my opinion, deter people who got autofilled from dodging after throwing threats around and just rejoining another game 5 minutes later to do the same thing to another player, as well as having the effect of making the potential troll feel like they are already on thin ice and shouldn't rock the boat, thus likely reducing instances of threats and attempted blackmail. as for other people who weren't autofilled who dodge simply keep the penalty the same since these days a lot of those dodges seem to be a defensive measure employed by players in my situation who are just trying avoid playing with people who are threatening to troll and feed because they got autofilled.

Just a thought..
