Ryan Gondoh now plays for Wealdstone.Some do. It has gone on for ages (in a surreptitious way). The sponsorship deals that YouTube deals get has led them to give other perks to their players (free boots/equipment etc).
As has been mentioned on this forum before, Lambeth All Stars’ front trio of Aaron Watson, Omari Hibbert, and Ryan Gondoh play for Whyteleafe in the Isthmian League. They also have some who are ex pros from Premier League clubs like Fulham and Sunderland.
