Oh wow, what an elaborate web of schemers and I am so glad you caught him or them red-handed. Fair play is always the way to go. Thank you @spectrumecons for taking swift action on someone or people taking unfair advantage over other participants in the challenges. These shameless people or person have to be called out and put in their right place. Being taken advantage of even for $1 is not fun.
No response from them or him means guilty as charged. Hopefully we will never see any of those accounts participating in future challenges.
Thank you for sharing and keep enjoying your week :}
