I see that as IMVU considering or noticing that these are new accounts and people are using it strictly to sell or their own benefit to send over to another account. Although they love to shut off godfather accounts, I agree they are pretty forgiving with some. I guess that comes down to... luck? They think you don't deserve a full perma ban yet so they give a 7 days, 30 days, something like that.
I have to mention that I don't think that tier levels can prevent a ban, seeing so many tier 7 getting banned lately. Mostly for selling credits or DMCA, but still. I think they are forgiving when it comes to an old account posting UFI, a new account they tend to ban on the spot because they have ways to notice it is a straight sock account.
