So I keep getting spammed by Picfair on "Exciting Offers" about big discounts on Picfair Plus. Now I haven't sold a single image on the site in 3 years. But does anyone have a Picfair Plus membership and has it helped in selling more than you do on the free account?

I mean, I don't mind paying a bit to an agency that treats contributors fairly if they actually make some good sales.

No more sales indeed, but the huge advantage is that you can redirect your domain there as your self-hosted website. And the membership fee is lower than any other alternative. Pity that Picfair does not make advertising...
