That's what I was told by admins on TS, and I trust their words.
Where common sense applies, I don't think many admins are really going to mind after round TKs except for excessive behavior. However, if it is a problem for you, it will be very easy for admins to deal with it. That's what I was trying to say. I think it would be a tad silly to enforce it harshly, since it can be amusing sometimes, but some people will be annoyed by it.
