I guess this has been the debate forever though. I mean I don't see anything wrong with people sharing their daily actifit progress even if that is all they are sharing. The problem comes when such posts are overrewarded for whatever reason. At least one app (maybe dbuzz? or leo threads?) has instituted a rewards cap on posts since it is designed primarily for short content. Maybe actifit should do something like this. Though some people do use it to create longer posts.
I don't really see anything wrong with cross posting either. I understand why people would get upset with reposting the same content on the same blockchain to milk rewards but that's something different. The whole idea of crossposting, or even taking old content from a previous blog or something would be to reach a new or larger audience. If that is frowned upon it makes it seem more like an anti-social network.
I think the main issue would be with Blurt. They have done their best to run a hit campaign against Hive. It's one thing if you disagree and you want to quietly do your own thing, but to poke the bear just seems shady to me. I used to do pretty text heavy actifit posts, it just got to be too much for the rewards I was getting. I couldn't justify it. It think putting a cap is a great idea.
