A player using alternate accounts to bypass a ban is not permitted. This was explained previously to the member in question, who has been warned in the past. We have several incidents of violation of forum rules on record for this member.
Only people involved in a sanction may discuss that sanction. Members do not moderate the forum, moderators do. Therefore if the member wishes to discuss it he should do so in the sanction report. Other players may not discuss it, regardless of how "draconian" they think a 48 hour ban on forum posting is.
The reason for the 48 hour ban has been explained already. Yes, it is subjective, but that is the nature of forum moderation. More than one or two moderators would describe your post as inflammatory.
Further discussion should take place in the appropriate thread.
