Is there a timeout on posting comments after creating a new account?

I created my RYM account a few days ago, and I’ve never posted any comments. I just tried to comment for the first time and I got hit with a pop-up saying I can comment in 7 days. Should I be concerned about my account being flagged as a bot, or is this just standard for new accounts? I’ve been importing all my ratings onto the site for the past few days, so I have been rating a lot of releases in quick succession. I’ve published a couple of reviews and that went fine so I’m not sure if this is account-specific. I just wanted to make sure I’m not going to be banned, because I am most definitely not a bot.
