Please take the limit off for entering codes or at least up the number entered to daily

Why is there such a tiny limit on how many codes we can enter every week? Why not up the amount that's weekly to everyday which I think it 75 points? I'm not sure if this is right or not so if anyone knows for sure let me know okay? Thanks. I am asking because the amount that is entered in doesn't really get to be spent on much very often which really sucks! Also, why are promoting twitter so much for the activities...shouldn't we have the option to put them out on FB too for the activity points? And what are activity points for any ways? What are the advantages to racking those up? Thanks in advanced for your help and answers!

PS I noticed some other people want the same thing and posted the same concern as mine but you have yet to answer their posts and this was a year ago!!???!!!?!? Should I just give up now or what? It doesn't seem likely I will get a response...
