Well, like I said, it wouldn't help with the ones like all-yugoslavia or giant-pile-of-hard-games person. But the full round of IPHs included a lot of stuff that wasn't actually super obscure, and was reasonably likely to have been the kind of stuff someone might have thrown in if they'd had to, like Snowpiercer or Transmetropolitan or Sharpe (or Murderbot.) But if there's a bunch of noms sitting around that nobody's planning to request, they soak up a bunch of offers that the stuff people actually want then don't get. Plus, of course, if people are nomming 6+ things themselves and only request those, they're less likely to add something that somebody else nommed that would make them more matchable.

No sock noms wouldn't magically solve it, but real participants offering and requesting other real participants' offers and requests are what makes the wheels turn, and the more fake noms you get the creakier it is.
