Ok. So we all know that all staff has the ability to check ip and see your other acc and see if u are multiclanning.
Most clans do not have a staff to help them find multiclanners (if they do not allow this in their clan)

So my suggestion is to make a thread where anyone can ask if a person is in another clan or not.
The answer will come from a staff and it will just be a Yes or a No and it will not include alt names or any other privacy things.

I think it is helpfull for clans to better pick worthy members
