Do not listen to any house when they talk about another's status. They will try to make their house look good while others look bad. This is 100% accurate and tells which houses are on probation.
Social probation means they can not have parties or functions. Disciplinary probation just means that they are being watched and should not break any rules.

That being said if a house tells you they are not on probation and they are on this list, they are LYING to you. You can find this information if you simply contact IFC on their website.
