So, you're saying that clones lower market prices. I'd say most of the players on TL are overpriced. I still don't get how a team would benefit. The player will be on TL for three days for all to see and bid. What perfect time are you talking about? Maybe you're talking about + 6000000 players that I know nothing of. Then the number of prospective buyers gets smaller. Still, I'd say it's impossible to guarantee a outside-bid-free transfer. It's impossible to claim that they cheat either. On the other hand, if you buy players off your team with another account, it's pretty obvious. And even automated? Even then some people are so illogical, so banning them by mistake might be taking them out of their misery.
