The affiliate program is interesting. So I just post the referral link to advertise your site, hope people click it, and contribute as both a seller and buyer?
But you have two links in there:
Is there a difference between them other than the length?
Also, is it safe that the user ID number that you identify my username with is in the referral link open to the public if posted?
PS: Hope you don't mind the offsite link to my website. I have no intentions of trying to drive traffic offsite as your fee pricing is very reasonable and I'm actually interested in the acquisition of bitcoins. The link is there to help validate myself as a seller given I have no feedback or verification on your site.
I think the longer ref ID is if you want people to know your name is attached to the account you're referring them to. If you didn't, you could just use the referral ID, which I don't believe is able to identify you.
For those referred, tosaki's done pretty well to prevent you from knowing who's bought what while keeping everything pretty transparent. You see the usernames of who you referred, but while I've tried (just to check!), there doesn't appear to be any way to definitively tell which user made which purchase, as all you see in the "commissions" window is which User ID made which purchase, but you are never given referred users' ID #. The commission window also gives the sales # when you're given a cut, but if you try to navigate to that order #, you'll get "You do not have permission to view this order." So, if you only have one or two users, you may be able to tell who bought something and how much they spent, but you're unable to tell what exactly they bought, and if you have many referred users, you'd have no idea what any individual was actually buying. The privacy protection there is pretty solid.
I've done a few transactions through BitMit. When I was originally trying it out around the beginning of the year, it was very clunky, and I often wouldn't get notifications of stuff happening, commissions would sometimes in weird chunks and sudden multiple credits, but now everything seems to be running buttery smooth. Tosaki's really made some incredible improvements over time on a great idea, and BitMit is a great asset to the community.
