Some of the best (or should we say worst) examples of this are shown off at "Regretsy" under their "Not Remotely Steampunk" tag. Faced with these hilarious mishaps of design, there is nothing left to do but bask in the Schadenfreude..
It's pretty clear most of this stuff isn't being made by people who are part of the steampunk community. Rather, it's just people whacking on a "steampunk" tag to get some extra traffic to their listing. Let such imposters face the slings, arrows and snark of the steampunks, I say!
