StreetBeefs takes applications through a Facebook group with seventy thousand people in it and no tryouts. King of the Streets takes them in a Telegram DM and wants your record and your street background. Top Dog in Moscow says, in its own words, that applications without competition footage are not read and that its queue holds several thousand. BKFC has never published a fighter email; the route is a form and a tryout in a city you have to find.
None of them publish what gets a yes. So most applications are a line: yo I wanna fight. One first-timer who did get on a StreetBeefs card wrote that he signed up far in advance, got his invitation three weeks out, and only knew he was picked when the location message arrived. Meanwhile someone else on a forum added the org on two platforms and was still waiting pages later.
The people who get matched are not the best fighters. They are the easiest to match: a real weight, one discipline, a date, and proof they will show up. That is a writing problem before it is a fighting problem, and it is the one this kit solves.
