Sola is another that I have played with. It does have censorship, I believe so they can attract advertisers. The developers seem to be having trouble working out what exactly makes their network useful and make some very bad decisions in the process. It was once called Plag and has a good community from those days. Now they try and award Sol coins which are worthless at the moment. I think it is a mixture between Instagram and Tinder. As with all these things time will tell if it amounts to much.
