The admin of this club are NOT going to admin they have done this.
The fact they have said it was discussed internally and the players left is paramount to admitting the rule was broken because either these couple of low rated players were pressured by their club members to leave or admin removed them. Much more likely admin removed them - because organising a couple low rated players to be online and messaged and removing themselves just prior to a match starting as many wouldn’t even know how to do is highly highly unlikely. Don’t think I could organise my lowest rated players to do that. 😎😎😎
If this isn’t acted on then effectively admin in this league can remove whoever they wish. And even get caught and it isn’t penalised.
You will never get more evidence than this unless admin admit doing this and they won’t.

As I wrote: It's undesirable, but not forbidden by the rules to put pressure on low-ranked players to leave a match.
