You sure try modlogs are public? Some already use the name “mod” to hide their own mod profiles when doing actions and it’s trivial to setup admin actions to remove posts / comments without listing them in the modlog, while I agree it’s better than nothing it’s still up to each individual instance to decide what they give price of their admin / mod actions.
Be careful and double / triple check on https://help.steampowered.com/en/accountdata what information is stored on your account, especially chats, payment information, purchases, subscriptions and so on. But I agree regarding TOS if they ever find out the account will be locked most likely.
