Clearly states that the point system can vary and/or change.

I've noticed my points haven't changed today despite my participation in posts and others liking or commenting on my posts. Something is definitely glitchy.

That sucks because I hear when you get to level 7 the prizes become epic? I'm guessing a PBR tall boy or a fish with feet car decal....hard to tell.
I also heard about a fella who looked like a Tom Cruise doppelganger who made it to level 11. That's one better than ten. No one tells you about level 11 but we all know it exists. Rumor has it Tom 2.0 is living in a cave in Nepal taping togeather the shredded dootles of Stephen Hawkin having run out of things to read or comment on here.....

I didn’t think points could go down once you’ve bagged them: That sucks! I HAVE noticed the system (admins) having slowed down in adding points after posts and such recently, sometimes by a day. Is someone asleep at the switch? Time for a peasant revolt?

The last few days I have noticed that when I post new items or comments in the morning my points do not change at all until later that night (or the next morning). Seems like the system might need a little manual intervention every now and then to update the point tallys.

Are they controversial? If you made some enemies you could have gotten blocked by some key people that you post on alot or some of the things could have been deleted where alot of your posts were. It could be that the points go away if the post is deleted along with your responses.
