Why this site is organised around rulesets

Most writing about kickboxing treats it as one sport with some regional variations. It is not. 16 distinct codes are in active use, and they disagree about leg kicks, knees, the clinch, throws, head punches, scoring and even footwear.

That disagreement is not a footnote. It determines which techniques a fighter ever learns, which champions are comparable, and whether a given statement about the sport is true at all. "Knees are legal in kickboxing" is true under some codes and false under others. So every page here declares the ruleset it is talking about, and every technique lists the codes that permit it and the codes that ban it.

Fighter records are read from a cited source and carry the URL they came from. 71 of 73 fighter profiles have a sourced record; the rest have the field set to null rather than an estimate.

The sourcing process runs four checks, each added because a specific wrong value got past its absence. The fighter name must match the page subject, including when a fighter's article sits under a later ring name. The record must come from a block explicitly anchored to kickboxing rather than a mixed martial arts or boxing record on the same page. Wins, losses and draws must reconcile against the stated total. And a total is never treated as a bout count, because Wikipedia infoboxes sometimes include exhibitions.

Anything that fails a check is cut rather than guessed.

No affiliate links in the equipment section, and no rankings dressed up as buying advice — each entry says what the item is for and which rulebook it belongs to. No invented citations. No claims about a fighter, a title or a date that could not be verified, and a visible null where verification failed.

Where the evidence disagrees with received wisdom, the site says so: shin conditioning is bone remodelling rather than nerve destruction, headgear reduces cuts without clearly reducing concussion risk, and most fighters do more hard sparring than the research supports.

Every page exists in English at the root and in Dutch under /nl, with hreflang alternates pointing at both. Dutch is not an afterthought here — the school that produced most of the modern sport is Dutch, and a site about kickboxing that only speaks English is missing half of its own subject.
