The whole point of the vacation option rather than the full blown ban is to give members the chance to see that we are serious without totally taking them off the site. In the past this was not an option. Once you were gone then you were gone. This is a little more of a friendly way to tell some people to tone it down a little. This gives members a chance to think about how to conduct themselves in the future. If the vacationing member could still communicate with other members that would really defeat the purpose. Hopefully the member will come out of vacation a little refreshed and wanting to be an asset to the community. If not then it will escalate the future penalties until we have no other option but to send them on their way.
