You can. I have done this for several already.
How to ignore users using the forum software
- Left click on your avatar on the top right
- In the new popup menu, left click on the top right person icon (the icons from L to R are a bell, bookmark, and person). when your mouse hover over the person icon, it will read preferences.
- In new popup window, left click “Preferences”
- In the new screen, left click users (it is on left panel)
- Add person to ignore list and set how long that you want them to be ignored.
It work well. I have found that trolls feed on the back and forth. This will make their posts hidden. Unfortunately, if someone quotes them, you will still seen that smidgen of quote text which will usually remind you why you put that particular user on ignore in the first place.
