One of the mods hasn't been online for three years, the other one for a month.

I submitted some runs 3 weeks ago that haven't yet been looked at.

Is there anything I can do?

I would first recommend reaching out to @phillip1872r via Discord/Twitter. If a reasonable amount of time passes without a response I would then recommend requesting moderation through here https://www.speedrun.com/the_site/thread/dueac/104 (make sure you have Email Authentication and platforms for contact first before doing this)

So, mods are completely gone from Speedrun.com. Now would be the time to let the site mods know through the support hub that you want to the mod for the game.
