By my count, in my comments I posted one link to a scientific preprint (noting that it was very questionable), 3 links to discussion of the scientific merits of that preprint, and 1 link to a scientific discussion relating to the structure of the 2019-nCoV virus. As well, my own little piece of entirely idle speculation, clearly and repeatedly indicated as being such and not as a fact.

By my understanding of the word 'rumour', as a native speaker of English, nothing here qualifies as a 'rumour' or 'rumour-spreading'.

A rumour would have the form something like 'I have heard that … (completely unevidenced claim)'.

FWIW, a tip back to you - telling someone else to shut up without explanation of what exactly it is you're referring to, or why you think they should shut up, is considered rude on any discussion forum, and also in real life conversations too.

Further, it encourages others to behave the same way.

For those reasons, please stop posting curt and rude shut-up messages anywhere on the internet. It is far more harmful to internet communities than anyone's idle speculation or references to discussions on other forums.

If you want someone to do something, anywhere in life, explain clearly what you want and clearly why. It doesn't need to be detailed but at least it should be clear. Being a polite netizen takes more than using the word 'please' at the start of a sentence.

Also, please do not expect other people to be able to telepathically intuit your mental state in a discussion, as nobody can do this, and please do not simply issue vague commands to other people, because it is rude.
