First of all, you used a steamID finder with an outdated API, so this isn’t your steamID. I would suggest using https://steamid.xyz/
Let’s move into your actual application.
1) You are inactive on the forums which is a shame.
2) your answer to Q. 16 (RDM sit) is in my views extra, unneeded, and wrong. You don’t need to ask every single person involved if you have the logs to prove mass RDM, furthermore you’re treating this like everyone is being civil, but you have to remember that the person in question is not complying at all. Apologizing to those who got RDM’d in some cases can lighten the punishment, but not in the case of MRDM. Also, you were supposed to include the ban time, but sadly you didn’t.
3) as stated above, you cannot reply to your own app. Luckily you hid that, so some won’t view it as an issue. I understand that it was in good faith, but you’re supposed to make the edit and move on.
My final thoughts are that you wrote a great response to Q. 15, and I wish you luck. Sadly I don’t believe that this is your time to become staff, but that’s okay. We all get denied our first time applying. What I would recommend you do is come out of this fresh, keep your head strong, and if you truly want to become stuff then you need to become more active on the forums and get more well known in game. Good luck, and I think that you can one day join the staff team if you improve in those few areas.
