i would just leave it there, since obviously they don't sell.. just sitting there gathering virtual dust.
the only ones you should be concerned about would be those which you made exclusive..
as i assume you want to submit them to other sites.
i don't know how many sites i still have an account with. when i started donkey years ago with finding leaf's site here, i submitted to literally every sites. but after months , years,.. i realised only ss is were the only two worth uploading, ..
a year ago, i think, can't remember, .. i had time to kill, so i went back to see those old sites,
they still have about 20 cents to 20 dollars earnings. most of them still waiting for reaching the
cash-out limit of much more than the present ss of 35 bucks.
things like that, makes me appreciate ss, even when at times , they become anal .
