I read portions of the book on BMF as well and can offer some more viewpoint. The Fleronys Enterprise should be a more accurate definition of the group since it's not a street gang but a DTO (Drug Trafficking Org). The brothers been active since the late 80s and Terry started a taxi cab company as a front for the enterprise. The F.E was well organized with the brothers being in a position of CEO, then 2 levels of Managers, on down to the drivers. They were more than just a loose band but exclusive collection of drug traffickers.

"no organized crime group would ever promote themselves with billboards, or t-shirts plastering their name"

Yakuza and 1% clubs says differ.

The brothers had 2 hubs with Terry in L.A and Meech in Atlanta but their enterprise was active in a dozen states. Meech was bringing too much attention with his flamboyance which was annoying his brother and of course the media will gravitate towards the flashy ones. The DEA have been on to the enterprise since the mid-90s and have been conducting raids against them. As early as 2000 is when the name of the label was brought since Meech was backing well known A-Town rappers. Meech side of the enterprise is what everybody know of but I'm more interested in Terry side and his partnership with the Crips & Pirus.
