1. We will NEVER explain management actions, especially not in public and even in private not to anyone to whom it doesn't concern. Its sort of similar to the "We don't negotiate with terrorists, argument. Forget about it, its never going to happen.
However it would be worth mentioning the funny stuff in all of this, the drama-act over here actually only got a suspension initially before he started creating so many IDs that it brought him under the radar and we found out how he would make a post then agree with himself from the other ID.
Multiple IDs = ALL of them get perm banned.
2. The suggestion about banning the free email IDs is actually good, its just that we've always tried to provide ease to people. Lots of newbies in the computer world in our part of the world. However you put it, hotmail/gmail/yahoo are what most of the world is dependent upon. We will try to find a middle route, perhaps force the user to sign-up on @defence.pk mails.
