By definition you can't accidentally queerbait. Queerbaiting is specifically using a same sex pair from the show to market the show to queer audiences with no intention of ever following through on a romantic relationship.

There is officially licensed Destiel merch signed off on by Kripke. Teen Wolf had a commercial with the actors for Derek and Stiles draped over each other talking about being "on a ship." Both shows actively used scenes between them as marketing while actively mocking fans for wanting them together. Sherlock has multiple characters refer to Johnlock as a couple, including characters we're supposed to believe are never wrong about human behavior and pushed those scenes in marketing. Then they acted insulted when fans saw them as a couple.

That's queerbaiting.

Done on accident it would just be queer subtext. Done because they had no other choice due to censorship is queer coding.

The specific meaning of the word is really starting to get lost and it's a pretty important one to keep accurate. It describes a very specific phenomenon that was done repeatedly and maliciously for decades and is meant to examine that specifically.
