Thanks for forcing me to expose the exploit. Now everybody is going to try to use it on all the campaigns. It is obvious why this doesn't require reporting to the administration: it's part of the system's design. It's not the activity that is being exploited, it's the signature campaign. The change implemented a few months ago made this the case and I've had to deal with it ever since. As the forum gets older, the opportunities for this grow so all I can do as campaign manager is stay sharp.
What change a few months ago? This isn't an exploit or a recent change but it seems you were unaware of it. To get your 14 activity points it has always been only one post is required and you could collect all the points at a later date.
Um, yes, but not always. Activity USED to be recalculated periodically and now it isn't. As pointed out by another poster:

I think you're confusing activity with the activity periods. The new period starts have always been the same every two weeks but you only have to make one post in it to get your full points if your post count is higher than your activity, but if not you can collect the rest at any time in the future providing you made a least one post in the new period. You can quickly 'boost' up your activity this way but this is how it's always been.
