I've yet to see any sales, but I've only been on the site for a week now. Can't say I expect any for a month or two.
As for the others, no. Hadn't even heard of a couple of those. I have trouble managing all the places I upload stuff to as it is lol. (Instagram, flickr, 500px, now this)
Don't give up and sales will come ;)
You should also sell on microstock websites (Shutterstock, Adobe Stock, Dreamstime, etc).
If you have a big portfolio (minimum 1k good images) it could be a nice little side income.
