They're kind of starting to grow on me as a threat.
Obviously we can't write about this on the wiki in detail, since it would be censored but it's been implied.
Basically, your chances of actually finding a member of the M.E.G in person is incredibly slim except for on particular levels, and you won't be able to stay with them anyway. The physical benefit gained by joining the M.E.G is nothing, you're still essentially alone, and your connection is not a guarantee.
However, you have to join the M.E.G if you want information on where you are and what's happening. This is a trap that ensures that virtually everyone who survives more than a week in the Backrooms is forced to join. At that point, the M.E.G is the driving force pushing you into the later levels.
Realistically, without the M.E.G, any level beyond 5 would be obsolete because virtually nobody would want to venture past the hellhole that is 6. However, with the M.E.G, people are literally forced to go into deadzones to look for potential places for a base with the information they need to stay alive on the line.
My only problem about it is the only information telling you this is the M.E.G page, logs, and the fact that the wiki belongs to the M.E.G and you have to piecemeal it together.
