How do I find out if my actions during a texas hold-em poker game were illegal or unethical?

I am tournament director for our poker site. we play a 11 months earning points to qualify for 8 semi-final games. the top 8 points earners during these 8 semis advance to the final table for a seat at the WSOP championship. During the 8th game I advanced to the final table but I was mathematically eliminated from making the final table. All of the other players at the table were friends of mine & I didn't want to eliminate any of them. I folded several winning hands during this game & 1 of the other players found out & is complaining about my actions. I need to know if my actions were illegal or unethical.
