If I copy the post into a new post, add new information to that new post, and delete the old post, it feels like I'm cheating my signature campaign (if I'm in one) by "re-using" last week's post content again for this week.
Maybe you noticed that one member was recently kicked out of signature campaign because he edited his posts and made big changes in them before week ending.
Nobody should not be forced to delete, copy-paste and edit their posts all the time if they want to bump the topic for some reason.
In my opinion this is not breaking any forum rules, but I would like to hear opinion of theymos and other moderators
(except mprep).
it certainly makes more work for campaign managers.
It can sometimes also create problems and errors with counting for managers, depending on time when bot makes this reports.
