DCF has a grudge against the Gardners

Recently here in Florida a mother tried to sell her 5yo child for $2000 The child had lived for the majority of its life with  foster parent couple (the Gardners) from the mothers church and today DCF rejected that home as a foster placement due to a conflict the family had with DCF in 2005. I dont know what the family did not qualify, but I they are licensed foster parent with currently place children, and the kid had spent his entire life with them. The choice to not place the child with them seems vindictive and not in the child's best interest. But hey..at least DCF got them back for whatever happened in 2005.
