People can add details that are not related to the actual profile person no matter how it is phrased. "Fact, Note, It is speculated, Hint" all make no difference as some people will just look at the source and not consider that it may not be accurate.
I have seen research notes that have been ignored and the information intended to disprove a fact used to support an Incorrect Connection, Date or Location. I have seen examples of 1940 US census records on someone who died in 1855 or a profile that had 45 separate references to 45 different FindAGrave memorials for his family members.
Yes some people will just glance at something and assume it is correct and the best way to try and prevent it is to show reasoning behind whatever is added to the profiles and hope that whoever comes afterwards takes the time to read the profile before changing things.
What is ideal is to use what Rootsearch adds and transform it into a proper Biography to expand and explain the sources you have found.
