It may have happened, but I doubt it's happened to *many*. And note that alkaline batteries can be easily turned into "hot steamers" too.
I would recommend buying 18650 from big, well known companies like Panasonic or Samsung, and only protected ones.
The $4 ones I've referred to are protected. As for who makes them, dunno -- my guess is that there's only a handful of factories and people just slap their brands on them.
