Two things I will put in here:

First, On Gotwoot there is no point in posting to "bump" your thread as if it died it's best to stay dead. There are many many examples of this. Also a User SHOULD be using the search feature if they wish to find your thread thats old and has not been posted in awhile. The only thread type that I would see this being useful is a personal thread about say, art or other creative works, however that type of thread is not really needed (We never really had a good personal art section anyways which is why I made a art site in the first place for gotwooters and others to use)

Second, Us staff have always had it be a good week or 2 wait before a double post can be done to bump a thread. This however is very rarely used as I explained in the first statement I have. As this condition is not something we do often, as well a action only done by the staff it is not added to the rules.

Bottom line: Don't fix something thats not broke.
