honestly, it's hard to believe that a player from series B is capable of joining these schemes, given that in a league like Italy, playing in series B is not a bad deal, on the contrary, players from series B have a decent salary and have a chance of playing in series A, I could believe that players at lower levels than in series B were doing this type of scheme because in the lower series the salaries are very low which encourages this type of schemes, because the players want money, they come to play in the very lower series where it will be difficult for them to move up in levels to B and A, that's why if someone gives them bad ideas like betting that in the game in which he himself will play he will have a red card and during the game he commits a purposeful foul to get a red card, then he will easily join this scheme when he sees the high amount of money he will earn because it exceeds his salary
That was definitely in the past, right now the world football is filled with greedy players looking to earn extra money from betting either personal or a collaboration with the casino or platforms to go and either score a goal or the most common one getting booked. This was a case for lower leagues in the past but even top tier players have of recent joined the play too. Not so recent two Ex Seria A players Sandro Tonali and Zaniolo were in the news for the same reasons with Tonali later found guilty and currently facing ban which could be extended due to another separate gambling Related cases again. The EPL had Ivan Tooney of Brentford suspend for six months and also fined him, so you see this whole thing has spread beyond Lowe leagues now too, one thing I will say is a more stricter rules are out in place for offenders such that even those attempting to commit same offenses will think twice
