We have good guidelines on answering in our Frequently Asked Questions as well as in the default help center in How to Answer pages. A good answer should address the doubts raised in the question. It should be written in such a way that the readers need not to check external sources or check external links to understand it properly. We have hundreds of such answers on the site. Some may not perfect but they meet standards of an answer like addressing the question, backed up with sources and properly formatted.
But I have observed a couple of answers written in a different manner. If some philosophical question is asked or a clarification of a controversy regarding a matter in our books is asked, the answer would be as follows:
< X and Y Sects > do not believe in < some concept > or < some topic >. This is only specific to < Z sects > This is only written in so and so texts which are not considered as canonical texts. These are not mentioned in the Vedas and Shruti which are the primary texts of Hinduism.
For more clarity, if the question asks about a practice or philosophy which is only specific to a sect of Hinduism.
Q: What are the rules to be followed by a Vaishnava devotee after performing tapta mudra?
A : Tapta Mudras are only specific to Dvaitans and Sri Vaishnavites. The practice is not followed by Smartas, Advaitans and other sects. This is not a common practice in Hinduism. Vedas do not mention it.
I know that counter argument to the question without explaining what is asked in the question is flaggable as Not An Answer. But under which category does the above answer fall? Should we allow such type of answers?
Is this a valid answer while clarifying philosophical questions and questions regarding clarifying some belief or a practice present in the texts? How should we deal with such answers?

Just to let you know, the answers I'm referring to were inaccurate and wrong. I pointed out how and why the answers are wrong. Wrong answers are a different matter and should be downvoted. Not flaggable. Totally misleading answers with unreliable content can be flagged for mod's intervention. This is the guidance I got from moderators.
