How do I delete an activity on my wall?
There is a delete button right below your post. But if you comment in a discussion or translate a document or level up, it seems like you cannot delete such news in your wall
Sometimes people ask this question when they are being harassed. If by any chance you are being harassed by another user, please know that Duolingo takes its guidelines very seriously. Anyone who uses Duolingo agrees not to harass others. www.duolingo.com/guidelines So, if anyone harasses you please feel free to use the white support button on the left or email firstname.lastname@example.org
If for any reason you are unable to file the report yourself (button or email broken, anxiety, etc.) you are welcome to contact a moderator (anyone with a green right around their icon) and ask them to file the report on your behalf.
If that person tries to delete evidence that they have harassed you, Staff will still be able to see it. So, file the report even if they delete it.
And if you see anyone else being harassed, please pass this information along to them or contact a moderator and let us know. Thank you! :)
