Limit to a single post per day is a big no...
What are we becoming then... And where is 'socialism" in all of that. :) I dont post every day, usually not even every third day. But sometimes I have urge to post stuff, and I end posting 3-4 posts in two days. And them go on days without posting again.
Maybe limiting number of selfvotes per day/week....
And, if I'm upvoting myself it will be 100% its me, i value my work and effort behind the things i write, and my stake is neglective. If i had>100k sp that would probably change.
I upvote myself at 100 percent nearly every day... I don't have any problem with people enjoying some of their own stake. I just can't understand those who want to earn without building a thing.
