I'm not sure either. I didn't see anything that would deserve a ban. But for the time being I lowered your warning level from 100% to 50%. Hopefully another Mod or Admin can shed some light on it.
Hi serpes your original account was possibly banned for hammering. We had some problems last month and your ip address was probably turning up in netstat way too much. If you had to make this post from a proxy then it is also possible that your ip address was perm banned due to suspicion of site attacks.
If you believe you have done nothing wrong then i will remove the ban on your account completely.
