From what I understand, DT, BS, and SS do allow editorial and FT, StockXpert, and iStock don't. Is this correct?

Also Cutcaster

i didn't mention this, as your question was THE BIG 6.
but if you mean every other sites after the Big 6...
another favorite where many micro contributors send their editorials ...  Alamy.

while BigStock claims to accept editorial, in reality they reect just about anything that they don't consider 'newsworthy' - ignoring probably the majority of editorial pix

DT and SS take about as many of my editorial as of fr,  and sales are similar to RF [including many rejected by BigStock]
