Well, there is not a limit for how many points you can get a day but I read this thread I saw that you will have a limit number of points per day for posting on other user's profiles. That will reduce spamming.
I see. Yeah, the wheel idea from Rrelja seems unfair indeed, but those comment maximum was something I didn't know, so thnx for that. Not that I comment on others a lot, not even once a day mostly. =P
