Can a member of Riot's staff help me identify and/or thank one of them?

In February of 2013, or very close to then, I had met a Riot employee at around midday while avoiding my schoolwork on a site called http://plug.dj . This was maybe a month after I had started playing League, and was also my first experience meeting someone who works at Riot. We were having a pretty good conversation when I had brought up LoL and he replied with a picture of him in front of the Riot office and a claim of being an employee. After that we chatted for a bit about League and he asked what skin I liked most, with my reply being Steel Legion Lux, her being the second champion I've ever bought and being a great deal of fun to play, and that skin being new and very desirable. Then after conversing some more, he requested my IGN, I replied truthfully and I remember him asking if the email linked to my account was legit and whether or not I was active with it, which it is, and I am. He stated later on that he would have to log off of plug.dj in a short while and that I should log on to my League account for a surprise. Since it was somewhat hinted at, but still very unexpected or unbelievable, I checked Lux to see if STL was available/owned, which it was. I then thanked him a bunch and asked if he could get on and play with me, but at that time he was still at work and could not play a match. To this day I've spent a fair amount of money on RP and have gotten several skins for myself and my brothers, but STL was the first skin I have ever had, and that Rioter started me off with a warm welcome to both the game and the community, and I still think of him occasionally.

Notes: ***** I feel like I'm a positive member of the community, at least in the in-game sense since I don't commune with other LoL players often out-game, and that this employee got me started by making me feel welcome and wanted in this game. ***** I also want to send my thanks to this employee, and don't want this message to impact him with any detrimental consequences. ***** On top of that, please don't revoke my skin (I wouldn't expect this, but I don't want any negative effects of this message to effect me either). It's a great story and memory, and I also love Lux and this skin, so I would be very unhappy to lose it. ***** Also, I believe he stated that he wasn't supposed to unlock any skins for other people, but I was new and he wanted to be inviting, which he was and I'm thankful for. (I have spent a good amount of money on this game due to him anyway, so if anything he made a smart investment for the company). ***** The Rioter is a man according to my memories, and in this story, but might be a woman. ***** Finally, he may be on my friends list, since I believe I have a couple Rioters befriended, but don't want to be wrong in asking them and have them be a completely different staff member altogether, or assign false thanks to someone undeserving, or who I don't intend to thank.

I do hope I can find the person who gave me such a good memory, through other Rioters and this site, or some different site like Reddit, or maybe a completely different attempt consisting of whatever I can come up with. But if you guys can help me, then please do, I've had this person on my mind on and off for a while, and I really do want to give proper thanks.
