Am I the only one that's had an abusive support? [ Note: No, I am not punished, nor was I rude ]

First off, no, I am not punished. Second, I appreciate supports who actually bother to try or are friendly, whether or not they do good, because I realize they get a lot of undeserved crap, and that it's a tough position sometimes.

Anyways. I was queueing up in Blind Pick as Jhin ADC with a friend who wanted to support for me (Lulu). Unfortunately, someone ninja picks support first, so she concedes and goes mid instead.

Game starts, enemy bot lane is Kindred + Sona. The game started off initially fine, and we almost got a double kill super early in thanks to her snare + my root + my execute fourth. As the game goes on though, I notice she's not using her Black Shield at all. I point it out with "morg pls", continuing with "You have literally one of the best spellshields in the game." I point out it'd help stop Kindred's E slow (and maybe the triple mark thing, not sure), as well as Sona's ult and her slow. She ignores me and continues to do whatever she wants.

At this point, I check the player summary (O key). She's building full AP, nor does she ward at all. I was mostly warding when I could, but obviously, sometimes they're on cooldown and I can't. I start to get irritated because she only tries to go for the damage or an execute before scurrying back. I say "You're not really a good support." At this point, she goes full out nuclear and starts ranting and bashing at me in both teamchat and allchat about how I'm just "salty", and how I need to "get good". I don't fall for the bait, so I don't bother flaming her back or otherwise trying to make any sort of deragatory remarks.

By this point, it's roughly mid-game, so I help between mid-lane, bot-lane, and occasional teamfights. Morg keeps wandering off by herself so I get curious and pan over with the camera to check what she's doing. Lo and behold, she wanders off into the middle of nowhere or straight into the enemy team, before standing still. Obviously, they find her eventually and kill her. While they're attacking her, she doesn't even bother to AA them, and simply waits for them to kill her. Once the death timer is up, she repeated that. Over and over. I still don't bother to flame her or otherwise make any even slightly discouraging or rude remarks towards her, nor do I ask for reports.

By this point, even the enemy team realizes something's wrong and they ask in allchat what the Morg is doing, to which I respond that we had a dispute and so she's intentionally feeding. I still don't flame her or ask for reports or anything else of the nature. They proceed to tell me in all-chat later that they've all decided to report her for intentionally feeding/trolling/etc of their own accord, and several members of my team tell me they'll do so as well. The game's not over yet though, and no one's made a surrender vote, so we continue playing anyways. With the exception of the Morg, everyone is actively trying their best (even the Udyr that wasn't doing so well and fully accepted the fact and apologized, to which I told him it's fine and not to worry so much). In addition, everyone was good-spirited and rather kind, so the rest of the game was fun, even if it was a crushing defeat, because playing with people like that actually helps make one enjoy the game.

So yeah. I just felt like it was a bit unusual, since the stereotype is that the ADCs are usually the abusive ones to the supports, and with this case, it was almost entirely the opposite.
