Low research questions are discouraged, although they don't have to be closed outright. However, there is a difference between "low research" and "beginner" questions.
"Low research" is something where the user had a very obvious source and didn't check it. For example, if somebody bought a new espresso automatic machine and asks us how to make cappucchino with it, instead of reading the manual which came with the machine, this would be a question with too little research.
But then there are also the basic questions. The first reaction by many people is indeed being annoyed at being asked something very basic - I have observed it in others, but also catch it in myself frequently. But for the site to work well, we should try to suppress/avoid this reaction. The reason: what is annoyingly obvious to one person is indeed hard for somebody else, and the answer is useful for many people. Sadly, many users don't think about it and tend to overlook and sometimes even downvote the simple questions, but this is not constructive.
The question you linked certainly shows that the OP has little knowledge of baking. In many cultures, these spatulas are ubiquitous, and it is hard to be a baker and not having seen them in a store or a book. But even if the OP lives somewhere where this type of spatula is uncommon, the shape and placement on the picture are suggestive enough for an experienced baker to guess the purpose. However, I think that this is just a beginner-level question and not a low-research question. First, there is no obvious source to consult. I don't know of a comprehensive manual of kitchen implements, at least not one readily available in the average household. Second, there is no way to make a simple Internet search. If the question was the other way round, "What are rubber spatulas used for", this could have been found with a web search. But in this case, the OP doesn't have any good search terms, because she doesn't know the name of the tool. So, I don't see any "low research" problem here.
Note that even if the question had been "what are rubber spatulas used for", this wouldn't have been a reason for closing. Sure, it is easy to find somewhere else. But we don't close questions just because the information is available elsewhere. If we had this policy, we'd have to remove the majority of our questions.
