I recommend contacting Mr.Tortellini first (since the SuperMod is basically uncontactable) through Twitch DMs (or maybe YouTube). If the user hasn't responded in a reasonable amount of time I then recommend using this form to request moderation (after following through the first post) https://www.speedrun.com/the_site/thread/dueac/116
Well, he doesn't list an email on his Youtube to contact and they got rid of the messaging feature. I could try to comment on his Youtube and see if he responds. His Twitch seems to not exist anymore. I don't really want to carry the responsibility of being a mod and I am not even sure the responsibilities that come with being a mod or if I have/need some sort of verification.
Ok, If you don't want to request moderation don't feel like you have to :) It's completely your choice. If you do however all you need to do is have Email Authentication and maybe add another contract method besides Discord. I'd give this a read if you're interested https://www.speedrun.com/moderationrules Also, if you ever change your mind, I can assist you with leaderboard moderating if you'd like ;)
