We should probably assume that this question is phrased and spelled as such to illustrate the same point.
This is one (of many) of the trouble areas that arise when you have a resource that everyone can help contribute to. Here we have many teams of members that work extensibility on trying to maintain the highest of standards. While having an almost unlimited number of contributors to answer questions, we only have so many that accept the task of "clean up" and maintenance.
We always do our best to encourage all of our contributors to try their best to answer questions to the best of their abilities. These abilities are different for different people. The contributor that knows the best answer for a question may not know all of the rules of grammar or have perfect spelling. We are a group and as a group we support each other to achieve the best quality we can in all of our questions and answers.

It may serve you well to not get too hung up on it as the internet is rife with "bad grammar"
Yes
