This blog is not so serious so treat it as such. Recently I looked into the standings of Codeforces Round #733 and for a few moments I thought I was tripping. There were 2 people with the name "Jiangly", that being jiangly and jiangIy, you can see the picture bellow ⬇

I looked for like 5 minutes straight at both their profiles and they looked exactly the same, the link was the same, everything. I actually started to believe that it was a bug. Fortunately, I didn't had the chance to post it on Codeforces and look like a completely looser as a few moments later it hit me, One is jiangly with lowercase "L" and one with uppercase "i", you can see the little difference in the link beatween the letters height but here on Codeforces their usernames look exactly the same.

So it's possible for 2 users to have the same username afterall, huh? :)

Disclaimer : I posted this just for fun and I hope you enjoyed this interesting observation! Cheers!
