Is it? My mistake. I suppose I'm used to the photo and tech worlds, where people pack their posts with referral links with no mention of it. It's just kind of assumed that happens. But ok, I shall edit the post to reflect that. Thanks for the tip.

Yeah I am a member of several of the lists, but I think at this point they are trying to charge too much and earn.com is still too small. If this idea keep growing, tho, they might start to be used. As for now it is mainly just ICO offerings every now and then at about a buck each.
