Message me I have done the work for you and I have found some hot young prospects for sale. Pay after you’ve gotten the player.

Hello, not sure this is legal tbh

Yeah, didn't find it explicitly written in game rules, but I feel like it should be ilegal.

Can ask the administrators

Game rules state that you have to abide to the French law, but I wouldn't think this would be a form of violation, but, on the other hand, I now nothing about French law.

This is solely my opinion

I assume that you are referring to the "senior" players and not youth players, but still don't think that it affects the following

I don't see a problem in sharing info about other players, especially if they are transfer listed (btw, I'm not advising it). Managers always have the option to reject an offer unless player is transfer listed and the offer matches the asking price.
But I do see a major issue with asking for a money in return.

I guess you could ask admins for their opinion if you want to.

Well here, he is talking about detections and youth players that are free agents until the end of the season, depending on the contracts he has seen offered by managers in the detection module. Sharing detection information for free is for sure not prohibited, but selling it is probably (i'd say about 80%) illegal. As fund transfers are prohibited in any form in the game, I can't see a way to pay for this information legally.

Additionally, on the French forum, you can't make an auction for a player who is not promoted to the main team. Since we are discussing non-playable players (those not promoted from the youth academy to the main team) and fund transfers, it's probably not legal..
