I see it all the time at low stakes cash games. This is how people earn a living

I've played for years, in locations all across the US, and know many other people who've played much more. This is basically not a thing. I encountered it once, decades ago, at Hawaiian Gardens in SoCal. If it's happening regularly it's very obvious, and the floor will quickly become aware of it. As far as making a living, it's easier to learn how to beat live low stakes than to successfully collude, and the latter would be unlikely to help much if you weren't already beating the games.

In low stakes cash games you don't have to collude to earn a living. The level of play is atrocious.

I've rarely met players whom I think could even act properly on the knowledge.

I've also never been in a room that wouldn't take it very, very seriously.

where? vegas?

I'd rather not give more hints to my location but an area with casinos

Ah yes, the fantasy of living near casinos and playing low-stakes poker cash games
