RICO isn't broad. The predicate acts of RICO are an explicitly enumerated list (see https://www.law.cornell.edu/uscode/text/18/1961 for the full list). Then there's the tricky part that the defendant has to be doing that on behalf of a particular enterprise. (See https://www.popehat.com/2016/06/14/lawsplainer-its-not-rico-... for a fuller description).

Most internet peanut gallery shouts of "RICO!" are not, in fact, RICO.
