My score varies quite a bit sometimes I am at level 5, and then it drops to level 3 and I didn't do anything.

Also I get that only five comments can be upvoted but do I lose points if i make 25 comments? Is there a limit to the number of resteems I can do? Are hunts that don't get approved a waste of my vote?

I understand you guys don't want to make the system easy to game and maybe these are all secret.
