Queued up into a game full of bot farmers I think?

So I queue into a co-op vs ai beginner bots just for fwotd, and immediately I notice all of my allies taking Ghost/Heal. I thought that was kinda strange.

We get into game, and one goes top, 3 go mid, and I just take bot because why not. The three that went mid (, , ) end up feeding the Annie 11 kills within the first 12 minutes. 11 kills to a beginner bot. NO players, no matter how new they are to League, do that badly. Also, they were randomly casting spells when no one was near and never used their ults ever. They never put up a fight and only shopped when they died. They also never talked once.

I don't know for sure if farm bots are illegal or not, but I would assume they are. Normally I wouldn't even bother reporting them, but I did so anyway because that BEGINNER BOT game took far too much effort. It was virtually a 2v5 the entire time (the one that went top, , I'm actually not sure if he was a bot or not. He actually started getting a lot of kills later on, but he still behaved erratically and never spoke once).

What are the chances of getting matched up with FOUR farm bots??
