TinkerCAD

Anyone else getting posted replies from this person? It's sexual in nature and when I get the email and I try to respond or view the post I get an error. "Error getting makes: Unable to load pinned comment at the moment. Click on block to reload page." When I reload you can't see the comment they made. They seem to be posting to every object I commented on previously.

I've emailed support but I don't know if they even exist. How are they able to still post if it's not showing up on the web page? How do I block them? I don't want to block Thingiverse on my email, just this person.

GRRRRrrr.

Have been trying to get a good circle.
I go to shape generators select cylinder, but it still has edges on it
Can you get a perfect circle ?

This STL was generated from a 2D PNG file using a website I found and When I import it into PrusaSlicer it works fine, however, when I import it into TinkerCAD it breaks up. Any suggestions as to what I'm doing wrong?
