6 jobs have closed among the 17 proposals I submitted. Most of them are 4 -6 connects. There is a lot of connects gone wasted. I don't think it's fair to a freelancer at all.
Think of connects like postage stamps. It doesn't matter if they hired or not, or even view your resume. You won't get the connects back. The only way you'd get your postage back is if the client cancelled the job (returned your mail), or it violated ToS (the company didn't exist and the post office sent back your mail).
