The pony spam is what I was referring to. The personal slander can refer to several things: one being what you mentioned, another being the onslaught of slander of several members via a personal chat on the users page, another being possible framing of other accounts, another being PM harassment. And the personal information leak refers to when the user who was involved with the personal slander posted detailed personal information they gathered via social network accounts (that the said user sought out themselves) of several users in chat.
The pony spam was met with VERY swift action and stern warnings... The latter incidents have been giving some users a headache over the lack of action from most mods.
I understand that most of the mods and admins have personal lives... but maybe they should choose a staff less busy.
I'd like to point out that when we warn members, we generally keep the warning/punishment between ourselves and the user(s) involved, so although it may not seem like we have done anything, we will have dealt with it, as long as it has been reported. The leaking of personal information case was dealt with shortly after it was reported, although some of the users here should consider being more careful about what personal information they put online. The link to the personal chat has also been removed from that users profile and we're currently looking at how best to deal with it, although we don't have much control over user's conduct on external sites.
