It's been quite some time

If I suddenly get a banned thing, it's probable that I was either pranked, or someone intended to play messy with reporting. Just declaring now I do not hack, nor cheat, as I do not see it as useful for playing games with friends. I was also told to add someone by the name of https://psteamcommunity.yuanyoumao.com/id/steamhelper111/ saying that "you have only 1 hour to add him to talk about the issue on your account", or else I'd get banned. I found this very suspicious... I added him, before the 1hour mark (from when said reporter started talking to me), and he declined (as shown by his invite no longer showing up on my pending list). Be weary of this person, I know not if I'm in online danger or not. If anyone would verify the validity of this user, please do so! Thank you.

NOTE
I was told this by the reporter, as she tried telling me that it was a mistake that got another one of her friends banned in minutes. Sending me this "https://steamusercontent-a.akamaihd.net/ugc/957478658528193675/C14507FFD6B9D9EF2D8DC7BE2AFD6A0E484A0C69/" showing what I can only call non-useful as it shows nobody but a message, and https://steamusercontent-a.akamaihd.net/ugc/957478658528196670/93D24B6D0837B0AD7D9911818B8A456A8FDA0B01/ this, which apparently is a video of her friend getting reported and banned right on the spot. I find this unusual - since none of the users yet mentioned have the URL name "a.akamaih". What makes me wonder, the user who reported me said "deathwish is my real friend now she already receive the banned already :/", yet this user is not on the reporters friend list (Idk if it would be, since the user has been banned.)

Also if I start acting unusual, test me on things only we'd know. Idk if adding him is a recipie for being hacked, but I dun want it to be! xd
