Bumping old THREADS is usually permissible. Its bumping old REVIEWS is where the problem comes in.
#13 - In our review forums, be mindful of the 'maturity' of threads you are posting to, ie. the date of the last item posted. We ask that you refrain from posting to a review in which the last post was made 30 or more days ago. Some exceptions may apply if you are providing relevant, valuable or updated information about the provider, but as a general rule of thumb, this can best be accomplished by writing a new review altogether and avoiding the bumping of old ones. This applies to our review forums, in particular, as discussion threads are often allowed to flow for an unspecified length of time.
No one really wants to visit a forum and see that padlock symbol going down every thread.
Its pretty simple, we post the rules of the board, everyone agreed to follow the rules as a member here, and when they don't, that's where a mod steps in to correct the situation. For reference, the link to the Forum Guidelines
