There is one footnote in the Cwiki about Kellie Andes without citation that Chris admitted that Kellie blocked him a few years earlier before the troll incident. I also found a link on the Cwcki of a 2010 correspondance between a troll and Kellie, but of note all it says is she hasn't seen him since high school.
So it's highly unlikely any of them talked to him, and if Chris is correct, he was blocked on Facebook by Kellie.
The "confirmation" of them being friends out of pity or pay comes from Barb not the gal-pals themselves. After the Troll Incident, Chris went to Barb and asked and she confirmed that what the trolls made up was actually real about them being paid or organized by Bob to be Chris' friend.
You can sort of tell from the CWCKI page about the 2010 Kellie Correspondance that she didn't really consider Chris as a friend really, just some guy she went to high school with:
