Thanks, if you want to PM me I'll check into it.
The reason for this policy is that we have a lot of young members and guests
We used to have a long list of xfire names so people could get in contact with people on that list.
Sadly we had not-so-nice people use that list to abuse people with profanity and threats and we decided we didn't want to be responsible for that. People are free to exchange PMs, xfire addresses and so forth, we just ask that they be careful and we no longer feel it's appropriate to publish a public list.
That's not to say that an adult officer might make his/her xfire available, and if someone in an unban requests posts their xfire we would probably not rush to remove it until we'd got in contact with them. But yes we probably should remove that if it's no longer needed.
Also I think we've removed the xfire box from the forum profile, so that it's not possible for a forum member to remove it - if they go into their profile, they don't see it so they can't blank it out. A forum admin has to do it for them. PM me the name(s) and I'll see what I can do.
