I have found several unwanted nonsensical hyperlinks inserted into unpublished content on my website (self-hosted WordPress). Four of these are to "#_msocom_1".
Googling on "#_msocom_1" returns 519 results; Googling on "msocom1" returns 602 results. I've checked a sample and all seem to be similar to my situation - they are nonsensical text inserted in the content (whether or not as a hyperlink). Unfortunately I can't find any explanation of why/how they occur.
Question: Have others noticed these nonsensical hyperlinks? Is there a known explanation? Does 'msocom1' actually mean something?
Note: I have not mis-spelled this term. It is 'msocom1'; it is NOT 'mscomm1'.
Addendum#1: there are/were other nonsensical hyperlinks. For example the words "content in" were turned into a hyperlink to 'http://content.in'. There are another 22 of these nonsensical hyperlinks.
