Too Bad I am just reading just this just now because I am launching my campaign in 3 days and there is no need to do all this now.
Is it possible to post a live campaign on these platforms just to drive more traffic to my actually campaign?
I have an indiegogo campaign, so I hope that won't be problem, since they mostly seem to focus kiccstater.
Another one I am aware if is
https://www.thunderclap.it/ It is very simple to use (if I can do it, anyone can!) but I wonder how easy it is to use the websites you mentioned.
