STRs have been mostly banned in the City of South Lake Tahoe since a voter initiative passed in 2018.  

Sure a house on the beach will make more at a STR than a LTR, but a typical house in a regular neighborhood (if STRs haven't been banned yet) will likely not. 

I would caution that many local communities have passed laws and regulations against short-term rentals, either banning them or curtailing them completely.

She is policing the forums and banning based on her emotions and her politics.

Is this allowed on Zillows platform or would they ban my account?

Basically the city wants to ban. 

My working theory is enough former prospects (usually out of spite for being unqualified) or unscrupulous competitors have reported your post, that the AI thinks you are a scammer, so you are essentially shadow banned. 

Zillow is banning properties that were marketed other places before being on their website. 

Once I got banned from the platform, everything started to spiral.

Woodland Park just voted to ban STRs within city limits.
