Honestly, at this moment I am kind of sceptical how this will play out.

Yes, its awesome that the comment spammers are out, we all agree on that!

But how will this work out for fresh starting minnows, who can only put themselves in the picture by leaving meaningsfull comments.

If they are maxed at a (name it) 10 comments a day because of their SP and RC this might be demotivating. I remember that in the beginning sometimes I would comment on 20/30 people daily with whole newspapers of info just to interact in a decent way
