Look for the Alert button on the Left side below the post if you get there before it's deleted. The Alert button is below the Rec button and below the Thread Info button. There you can report the alert.
If that doesn't work you can send DU mail to the host of the forum or group you're in. Click the Name of the group. I used Community Help as an example here.

Click the "About This" button which you will see has a lower case "i" surrounded by a blue circle to find out who the Host or Hosts might be. But not every place has a host. So...
If that's not an option you can DU mail EarlG directly by searching for him,
https://www.democraticunderground.com/?com=search&terms=&author=EarlG&forum=1256&type=title&startmonth=2&startday=8&startyear=2023&endmonth=3&endday=8&endyear=2023&sortby=date
Then click on one of his posts to find his moniker
https://www.democraticunderground.com/
In this case I used the first thing that came up in the search.
I clicked through to the post he made.
https://www.democraticunderground.com/?com=view_post&forum=1256&pid=21408
Then I clicked on his moniker which took me to his journal
https://www.democraticunderground.com/~EarlG
Then I selected the option to send him a direct message which is represented by a picture of a pencil with an eraser and a yellow envelope and says Send DU mail.
Click that and you get
Send DU Mail to EarlG
Here's a link for you to the send mail option for him...so you don't have to follow all the steps this time, I did it for you.

Good luck! I hope this helps.
