Personally, I do not think snap does anything with tasted domains. They pick up what's dropping from there partners. The ones that have backorders go to auction and the ones that do not get backorders go to Public Auction. I really do not think they would search for Forced Drops, because snap deals with the premium domain market and they know if a domain is forced dropped, it's not good anyways. imo
Do some get tasted and dropped thru there Public Auction, Yes, but when they are redropped, snap doesn't repick them back up.
