Of the new ones I get emailed, anything with three shots of a young lacklustre Romanian in sexually-inviting poses is ignored. As does anything which is clearly "photoshopped" - you can easily tell these after a while, too good to be true and where the back- and foreground don't marry.
Anything that interests me goes in my "New Talent" hotlist for monitoring purposes - I'd want to see what sort of FB they get first, though if they're Polish and perhaps Czech I might (notionally) consider trying them out to TOFTT (risk your money on a rank outsider so you can report back to the UKP community on the outcome).
Don't think it matters if they get the "Legitimacy" warning showing, this will just be based on an unknown algorithm in the software and everyone has to start somewhere.
