I run a 12-team keeper league, going on 11 years now. A few owners have been there since the beginning. So Owner A has gotten into it a few times with Owner B over the years and has generally complained whenever he speaks. However, since being around since day 1, I've let Owner A stick around. There's been some talk among other league owners that he should be removed because of his negativity.
So Sunday night, we're discussing the draft times for this year, and a few owners ask me to make it 3pm the day of because of work concerns. Owner A gets upset and says "we always do it at noon, and I don't want to hang around all day, I have things later". Owner B and Owner A get into an argument on the group page because Owner B rips him up a bit about it and Owner A does not respond well.
An hour later, I get a text from Owner C saying he has made a trade with Owner A, where Owner A is trading Buster Posey ($20) and Yu Darvish ($19) for Josh Hamilton ($25), Desmond Jennings ($19), Salvador Perez ($19) and Justin Masterson ($3). Owner A has said for a long time now Darvish is "untouchable". I confirm the trade with Owner A but I have some suspicions and I ask Owner A if something is going on. He says no, just post the trade. Owner C says hes been trying to get these players for a few seasons now when I ask him if anything is up. So I allow the trade. I've had a policy to never veto a trade unless collusion is involved, and I only had that incident once in 11 years.
Owner A sent me a message resigning from the league today.
This leaves me in a bit of a pickle. Do I allow this trade to stand? I don't have any proof that these two colluded together. But at the same time, is it possible Owner A knew what he was doing before he did this trade and did a favor to this owner on the way out? Is it unfair to punish owner C if he didn't act with malice? Another issue is that owner C has made another trade since, so I would have to void both trades since he might've not made that trade if the first didn't happen. I've talked to a few league owners and I got a mixed reaction, so I'm hoping to get some good advice here. Thanks!
