This question starts was prompted by [a note of caution](https://hinduism.stackexchange.com/questions/4127/difference-between-the-shiva-purana-and-the-linga-purana/4142#4142) given by user Keshav Srinivasan which reads:

> 
> One note of caution: it's believed that the Linga Purana contains a lot of interpolations, because other ancient works which quote the Linga Purana quote things that are not in the actual text we have and don't quote things which are in the text we have. This leads some people to believe that the Linga Purana we have today is a complete interpolation, but it could just be that it contains so many interpolations that the overlap between content quoted in other works and content preserved is negligible. See page 93 of this book for details.

I've observed similar cautionary notes elsewhere in the past. For example:
[Here:](https://hinduism.stackexchange.com/questions/6508/do-we-have-any-details-about-the-oldest-idol-of-any-hindu-god-found-anywhere-in/6512#6512)

> 
> the Shiva Purana suggests that it happened close to the time of creation, but there's reason to believe that the account found in the Shiva Purana is a later interpolation.

> One note of caution: references to Ganesha in ancient Hindu scripture are few and far between, since Ganesha only rose to popularity later on, so there is a possibility that this may be an interpolation in the Brahma Vaivarta Purana. (I raise a similar issue in my answer here concerning a passage in the Shiva Purana.)

Now, I must confess: I find these notes insulting; to my reading, saying that Linga Purana is completely interpolated is an insult to Sãdhakas who are doing various Sadhanas and to devotees who are worshipping Parameswara with hymns of Linga Purana. 

That said, I recognize that Hinduism Stack Exchange is *not* a place of worship, but rather a venue for documenting - as accurately as possible - the nature of belief and worship. 

So my question for all of you is: can such cautionary notes be considered informative and preserved, or should they be be seen as potentially divisive opinions and removed?
