Each match with full match data gets an estimated probability that it was a win trade, based on how the opposing team played during the match.
How to read it. Win trading is impossible to avoid completely, so teams will always show up on this list. A few probable trades doesn't mean a team is win trading. But if a team's Share of Matches is 20% or higher, it is very likely win trading.
Disclaimer. The percentages are automated estimates, not proof. They measure how closely a match resembles ones that were judged to be win trades. They do not show who arranged a match, and a disconnect, a no-show or an AFK player can look identical to a trade. Being on a team's roster does not mean a player took part in any trading. Use this as a starting point for your own review before reporting anyone, and do not treat a percentage as a verdict.
