Post in SD next time, if you find yourself unable to contact a staff member. The moderator that banned you has probably forgotten to set the time limit, as bans are permanent by default. You have hardly any reason to complain though, as I'd have given you a permanent ban for linking to pornographic content.
Even so, I have unbanned your account, and will ban this one to prevent future abuse.
Do keep in mind you have been given two warnings and a temporary ban. Next time you break the rules, you will be permanently banned from SRF.
