Maybe it is the mention of some of the moderators to pay attention to your appeal. Only one of them can unban your account.
For example, Cyrus or hilariousandco
Let's see when they unban this account or how much time they would take to unban. Perhaps a PM to the mods may help. Global moderator needs to do this job as asked by xandry on Feb 26.
It could take some time, they've definitely seen it. There might be some investigation involved to decide the outcome, but I'd be quite confident in saying that they've seen the appeal or perhaps they've decided against lifting the ban.
Ah, the same old "blame it on developers" excuse that we heard so many time before in the past. But even if it was indeed their fault and they put it there without your approval, you didn't think that its misleading to keep that logo on your website because you simply weren't listed there as of yet?
The fact that someone else had to warn you about that says something.
It shouldn't have been made live, although it's mad how many times I've heard this excuse. Usually, developers that you've hired will give you a preview before going live, and you work out the fine details, and eventually make it live. However, there's usually a review process, and ultimately your responsible for who you hire, and what you put out.
Since, I haven't looked at exactly what was copied, and the exact situation since it needs someone with the correct permissions, I don't know how complex the situation is. So it might take a little bit for it all to be reviewed.
