In all honesty, Deathbed's working method seems pretty realistic. For unknown Harsh Noise (Wall) artists, an edition of 25 is okay - some "real" CD pressings may sell even less copies than 25. The bigger projects seem to be decently limited, i.e. 50 - 70. For a label that doesn't trade a lot, that is also realistic. May be a bit too small, but some labels don't want there homes cluttered with leftovers that don't move.
Same goes for advertising. IG is popular with people who actually buy the product and it is understandable that labels use it. Of course, the bigger and long-established labels may not need IG (or even Facebook), but a new label needs exposure.
Quality is of course a highly subjective criteria. Scrolling through his discography, I see some unknown acts, some new promising ones that I personally know and like and some more established ones. Also pretty okay, if you keep in mind that the biggest and most popular projects either have their own labels or safe deals with the "big ones".
Personally, I find the idea of a label that knows its capacities and customers more charming than those who move the majority of their copies by sending dead stock to any distributor they are aware of (who oftentimes just accept trades to be kind). It may seem marginal, but this is the reality of Noise. People would be shocked how low the sales of even more established artists can be nowadays.
