As a note, just because I add someone to my friends list and play a couple games with them does not make them my "friend". I am a friendly guy who is happy to meet people in game and have duo queued with many people I don't know all that well, but am happy to keep on my buddy list. The guy in question is more of a "friend of a friend". I'm better "friends" with Jaximus - and this guy is his friend.
If people think that that entitles them to special privileges or that they can name drop me... well, they got another thing comin (as Jaximus saw when his main account got banned and now doesn't get end of season rewards).
There's a difference between "being my friend" and "being someone on my buddy list" who I have duo queued with. One potential reaction would be for me to stop duoing with people I don't know super well - but in the same way that Riot doesn't take the "safe" road with engaging with our community, in that we encourage all Rioters to interact with the LOL community rather than hiding behind a PR wall - I'm not going to stop playing with people because one dude got ahead of himself and name dropped me.
But - don't believe the hype. If people are toxic, they'll get banned. Period.
If some people put on their good guy hat in my presence, but are toxic elsewhere, they'll still be caught in the system.
You guys calling attention to this stuff is helpful - so keep it up.
