British doubles number one Tara Moore spoke out against Djokovic's PTPA for what she perceived as favouritism.
The organization was founded on the principle that it will represent all tennis players regardless of status and ranking. It's a noble goal by Djokovic and Pospisil who were the players that started it all but the organization missed a chance to back up those claims.
Earlier this year Tara Moore got suspended for a similar reason to Halep. She maintained her innocence but the PTPA never reached out to her or offered help. They did that for
Simona Halep who recently got provisionally suspended for doping.
Moore explained that the silence of PTPA, when questioned about not speaking up for other players, speaks volumes:
"Their silence tells you everything."
She then posted a status on Twitter sarcastically thanking the PTPA for helping her.
