So what's interesting about your case is you don't have a record of a ban appeal for your first unban. Looking at it first glance I thought it was me, but checking it whoever did it didn't know what they were doing as they left the IP bans on the other accounts.
I have a feeling this is the unban appeal that got sent to admin reports by accident so no one can see it apart from Kevin. Unless you remember which admin undid it or if you did for an unban appeal, the mystery won't be solved!
So since you live in a country that is notorious for recycling their IPs you're going to run into this problem often than others. I've removed the IP and account ban. Next time this happens, please just message me. Don't message ashton to message me, I'm not fond of middlemen!
