Just some info from a fellow low tier:

I uploaded this design, PESTILENCE 2024, which was under review and denied with the text "Interconnectivity has brought with it an age of pestilence and plague. This very likely won't be the last coronavirus to spread throughout the globe, so pick up this edgy design before the next one starts. Vote Pestilence 2024, the horseman for our times!"

I'm pretty sure it's because it said coronavirus.

Next I resubmitted it with no description but the same PESTILENCE 2024 title and it was approved right away.

Now I'm playing with the bulletpoints but avoiding any coronavirus words and it's working fine.

Did you include a description with a troublesome word?
